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.
