Replaces them with forward declarations of used types, or removes them entirely if they aren't used at all. This also replaces certain Common headers with less inclusive ones (in terms of definitions they pull in).
This makes the code cleaner and also leads to some user-visible changes:
The wx game properties will no longer let the user
select WAD languages that don't have any names.
The Qt game list will now display names using the languages
set in the configuration instead of always using
English for PAL GC games and Japanese for WADs.
If a WAD doesn't have a name in the user's preferred language,
English is now selected as a fallback before Japanese.
Prior to this refactor, certain options would cause the game list to refresh when the config modal dialog is closed (such as adding a folder to the path list). This restores that functionality.
Prior to this, ConfigMain.cpp was a large (52KB) cpp file that contained all of the UI setting code.
This breaks up the config code into subclasses of wxPanel, which are then just instantiated to add to the settings wxNoteBook. This keeps all the settings categories separated from one another and also cleans up the code in general.
