Allow spaces and capitals in script names when loading

This lets any script name use capitals and spaces all they want, while
still being able to jump to them via iftrinkets() or similar.

The issue is that whenever tokenize() is ran, all spaces are stripped
and every argument is lowercased before being put into `words`. So, the
solution here is to create a raw_words array that doesn't perform space
stripping or lowercasing, and to refer to that whenever there's a script
command that loads a script. We keep the lowercasing and space removal
elsewhere to be more forgiving to newcomers.

This is technically a forwards compatibility break, but it's only a
minor one, and all levels that utilize it can still be easily modified
to work on older versions anyway.
