De-duplicate copy-pasted input/render code in menus
This removes duplicate code that came about as a result of various possible permutations of menu options, depending on being M&P, having no custom level support, having no editor support, and having MMMMMM. The menus with such permutations are the following: - main menu - "start game" is gone in MAKEANDPLAY - "player levels" is gone in NO_CUSTOM_LEVELS - "view credits" is gone in MAKEANDPLAY - "game options" - "unlock play data" is gone in MAKEANDPLAY - "soundtrack" is gone if you don't have an mmmmmm.vvv file - "player levels" - "level editor" is gone in NO_EDITOR I achieve this de-duplication by clever use of calculating offsets, which I feel is the best way to de-duplicate the code with the least amount of work, if a little brittle. The other options are to (1) put function pointers on each MenuOption object, which is pretty verbose and would inflate Game::createmenu() by a lot, (2) switch all game.currentmenuoption checks to instead check for the text of the currently-selected menu option, which is very error-prone because if you make a typo it won't be caught at compile-time, (3) add a unique ID to each MenuOption object that represents a text but will error at compile-time if you make a typo, however this just duplicates all the menu option text, which is more code than was duplicated previously. So I just went with this one.
