Fixed AudioManager/InputManager unsigned vs signed comparison warnings. Fixed a FolderData sorting crash (I can't believe nobody's reported this). Fixed a GuiTheme crash for empty paths. Added the %ROM_RAW% tag, for the unescaped ROM name - useful for higan on windows. SystemData will now add folders that end in EXTENSION as GameDatas, and not recurse through them. Also useful for higan.
