Clean up and prevent unnecessary qualifiers to self By "unnecessary qualifiers to self", I mean something like using the 'game.' qualifier for a variable on the Game class when you're inside a function on the Game class itself. This patch is to enforce consistency as most of the code doesn't have these unnecessary qualifiers. To prevent further unnecessary qualifiers to self, I made it so the extern in each header file can be omitted by using a define. That way, if someone writes something referring to 'game.' on a Game function, there will be a compile error. However, if you really need to have a reference to the global name, and you're within the same .cpp file as the implementation of that object, you can just do the extern at the function-level. A good example of this is editorinput()/editorrender()/editorlogic() in editor.cpp. In my opinion, they should probably be split off into their own separate file because editor.cpp is getting way too big, but this will do for now.

Separate includes into sections and alphabetize them Okay, so basically here's the include layout that this game now consistently uses: [The "main" header file, if any (e.g. Graphics.h for Graphics.cpp)] [blank line] [All system includes, such as tinyxml2/physfs/utfcpp/SDL] [blank line] [All project includes, such as Game.h/Entity.h/etc.] And if applicable, another blank line, and then some special-case include screwy stuff (take a look at editor.cpp or FileSystemUtils.cpp, for example, they have ifdefs and defines with their includes).

#include "Map.h"
Remove unnecessary includes from header files Including a header file inside another header file means a bunch of files are going to be unnecessarily recompiled whenever that inner header file is changed. So I minimized the amount of header files included in a header file, and only included the ones that were necessary (system includes don't count, I'm only talking about includes from within this project). Then the includes are only in the .cpp files themselves. This also minimizes problems such as a NO_CUSTOM_LEVELS build failing because some file depended on an include that got included in editor.h, which is another benefit of removing unnecessary includes from header files.

Clean up unnecessary exports and add static keywords This patch cleans up unnecessary exports from header files (there were only a few), as well as adds the static keyword to all symbols that aren't exported and are specific to a file. This helps the linker out in not doing any unnecessary work, speeding it up and avoiding silent symbol conflicts (otherwise two symbols with the same name (and type/signature in C++) would quietly resolve as okay by the linker).

Fix resumemusic/musicfadein not working It seems like they were unfinished. This commit makes them properly work. When a track is stopped with stopmusic() or musicfadeout(), resumemusic() will resume from where the track stopped. musicfadein() does the same but does it with a gradual fade instead of suddenly playing it at full volume. I changed several interfaces around for this. First, setting currentsong to -1 when music is stopped is handled in the hook callback that gets called by SDL_mixer whenever the music stops. Otherwise, it'd be problematic if currentsong was set to -1 when the song starts fading out instead of when the song actually ends. Also, music.play() has a few optional arguments now, to reduce the copying-and-pasting of music code. Lastly, we have to roll our own tracker of music length by using SDL_GetPerformanceCounter(), because there's no way to get the music position if a song fades out. (We could implicitly keep the music position if we abruptly stopped the song using Mix_PauseMusic(), and resume it using Mix_ResumeMusic(), but ignoring the fact that those two functions are also used on the unfocus-pause (which, as it turns out, is basically a non-issue because the unfocus-pause can use some other functions), there's no equivalent for fading out, i.e. there's no "fade out and pause when it fully fades out" function in SDL_mixer.) And then we have to account for the unfocus-pause in our manual tracker. Other than that, these commands are now fully functional.

Don't reset entire musicclass when mounting and unmounting assets musicclass::init() re-initializes every attribute of musicclass unnecessarily, when initialization should be put in a constructor instead. This is bad, because music.init() gets called whenever we enter and exit a custom level that has assets. Otherwise, this would result in a bug where music.usingmmmmmm would be reset, causing you to revert to PPPPPP on the title screen whenever you enter a level with MMMMMM selected and exit it. This also causes a confusing desync between game.usingmmmmmm and music.usingmmmmmm since the values of the two variables are now different (these duplicate variables should probably be removed, too, and a lot of other duplicate variables like these exist, too, which are a real headache). Which means despite MMMMMM playing on the title screen, exiting the game and re-launching it will play PPPPPP instead. What's even more is that going to game options and switching to PPPPPP will play PPPPPP, but afterwards launching and re-entering will play MMMMMM. Again, having duplicate variables is very bad, and should probably be fixed, but that's a separate patch.

Allow using help/graphics/music/game/key/map/obj everywhere This commit makes `help`, `graphics`, `music`, `game`, `key`, `map`, and `obj` essentially static global objects that can be used everywhere. This is useful in case we ever need to add a new function in the future, so we don't have to bother with passing a new argument in which means we have to pass a new argument in to the function that calls that function which means having to pass a new argument into the function that calls THAT function, etc. which is a real headache when working on fan mods of the source code. Note that this changes NONE of the existing function signatures, it merely just makes those variables accessible everywhere in the same way `script` and `ed` are. Also note that some classes had to be initialized after the filesystem was initialized, but C++ would keep initializing them before the filesystem got initialized, because I *had* to put them at the top of `main.cpp`, or else they wouldn't be global variables. The only way to work around this was to use entityclass's initialization style (which I'm pretty sure entityclass of all things doesn't need to be initialized this way), where you actually initialize the class in an `init()` function, and so then you do `graphics.init()` after the filesystem initialization, AFTER doing `Graphics graphics` up at the top. I've had to do this for `graphics` (but only because its child GraphicsResources `grphx` needs to be initialized this way), `music`, and `game`. I don't think this will affect anything. Other than that, `help`, `key`, and `map` are still using the C++-intended method of having ClassName::ClassName() functions.

Clean up and prevent unnecessary qualifiers to self By "unnecessary qualifiers to self", I mean something like using the 'game.' qualifier for a variable on the Game class when you're inside a function on the Game class itself. This patch is to enforce consistency as most of the code doesn't have these unnecessary qualifiers. To prevent further unnecessary qualifiers to self, I made it so the extern in each header file can be omitted by using a define. That way, if someone writes something referring to 'game.' on a Game function, there will be a compile error. However, if you really need to have a reference to the global name, and you're within the same .cpp file as the implementation of that object, you can just do the extern at the function-level. A good example of this is editorinput()/editorrender()/editorlogic() in editor.cpp. In my opinion, they should probably be split off into their own separate file because editor.cpp is getting way too big, but this will do for now.

Move musicclass cleanup to separate function musicclass::destroy() This removes the music cleanup code from musicclass::init(), and requires that we also call destroy() in Graphics::reloadresources(). This is because we'll need to re-use the musicclass cleanup code elsewhere, and we don't want to copy-paste the cleanup code. Or at least, I don't (but I'm not a game dev, game devs copy-paste all the friggin' time).

Fix resumemusic/musicfadein not working It seems like they were unfinished. This commit makes them properly work. When a track is stopped with stopmusic() or musicfadeout(), resumemusic() will resume from where the track stopped. musicfadein() does the same but does it with a gradual fade instead of suddenly playing it at full volume. I changed several interfaces around for this. First, setting currentsong to -1 when music is stopped is handled in the hook callback that gets called by SDL_mixer whenever the music stops. Otherwise, it'd be problematic if currentsong was set to -1 when the song starts fading out instead of when the song actually ends. Also, music.play() has a few optional arguments now, to reduce the copying-and-pasting of music code. Lastly, we have to roll our own tracker of music length by using SDL_GetPerformanceCounter(), because there's no way to get the music position if a song fades out. (We could implicitly keep the music position if we abruptly stopped the song using Mix_PauseMusic(), and resume it using Mix_ResumeMusic(), but ignoring the fact that those two functions are also used on the unfocus-pause (which, as it turns out, is basically a non-issue because the unfocus-pause can use some other functions), there's no equivalent for fading out, i.e. there's no "fade out and pause when it fully fades out" function in SDL_mixer.) And then we have to account for the unfocus-pause in our manual tracker. Other than that, these commands are now fully functional.

Clean up music handling to one place Previously, setting the actual volume of the music was all over the place. Which isn't bad, but when I added being able to press N to mute the music specifically, I should've made it so that there would be a volume variable somewhere that the game looks at if the music is unmuted, and otherwise sets the actual volume to 0 if the game is muted. This resulted in things like #400 and #505 and having to add a bunch of special-cased checks like game.musicmuted and game.completestop. But instead of adding a bunch of special-case code, just make it so there's a central place where Mix_VolumeMusic() actually gets called, and if some piece of code wants to set the music volume, they can set music.musicVolume. But the music handling logic in main.cpp gets the final say on whether to listen to music.musicVolume, or to mute the game entirely. This is how the music handling code should have been from the start (when pressing N to mute the music was added). Fixes #505.

Don't manually write out INBOUNDS_VEC() checks This is because if they are manually written out, they are more likely to contain mistakes. In fact, after further review, there are several functions with incorrect manually-written bounds checks: * entityclass::entitycollide() * entityclass::removeentity() * entityclass::removeblock() * entityclass::copylinecross() * entityclass::revertlinecross() All of those functions forgot to do 'greater than or equal to' instead of 'greater than' when comparing against the size of the vector. So they were erroneous. But they are now fixed.

Add bounds checks to script commands that didn't have them Continuing from #280, another potential source of out-of-bounds indexing (and thus, Undefined Behavior badness) comes from script commands. A majority of them don't do any input validation at all, which means the potential for out-of-bounds indexing and segfaulting in custom levels. So it's always good to add bounds checks to them. Interesting note, the only existing command that has bounds checks is the flag() command. That means you can't turn out-of-bounds flags on or off. But there's no bounds checks for ifflag(), or customifflag(), which means you CAN index out-of-bounds with those commands! That's a bit bad to do, so. Also, I decided to add the bounds checks for playef() at the musicclass::playef() level, instead of just the level of the playef() command. I don't know of any other cases outside of the command where musicclass::playef() will index out of bounds, but musicclass is the one containing the indexed vector anyway, I wanted to cover more cases, and it's better to be safe than sorry.
