Added additional game/language support.

Now Pokelib works with all released Gen 1 games, in all languages, and it should work with most ROM hacks, too.

Please note that Yellow will freeze upon trying to continue a R/B save file (although it'll initially load it fine and you can use New Game). Red, Green and Blue (JP) will freeze after the title screen, and this appears to be an emulation issue. FR/DE/IT/ES Red/Blue can load an English R/B file fine.
