This commit adds most of the code changes necessary for making the game translatable, but does not yet "unhardcode" nearly all of the strings (except in a few cases where it was hard to separate added loc::gettexts from foundational code changes, or all the localization- related menus which were also added by this commit.) This commit is part of rewritten history of the localization branch. The original (unsquashed) commit history can be found here: https://github.com/Dav999-v/VVVVVV/tree/localization-orig
