Progress on Implementing Dungeon Packs
Added code for parsing dungeon pack config files. The settings for our built-in dungeons are now read from a file instead of being hardcoded. One or two settings aren't being accessed yet and we still don't search for other dungeon packs in the custom dungeon folder. That'll come in another commit.
