This adds Pikachu, Cat, and "Small Bird" menu icons. The cat has a custom animation done by myself.
The Jigglypuff in the Pokemon Centre now uses the new sprite, nice 'n' pretty. Officer Jenny is also in Cerulean. The Pokemon from Melanie's house in Yellow have been put in Mr. Fuji's House, given the purpose of the house in RB is different. I think it ends up fitting very nicely.
Chansey has been given its proper sprite in Fuschia. Yellow didn't actually do this, as Chansey doesn't have a walk cycle, causing the stuff that exists to go unused. I wanted it, though, so I had Chansey just not walk and turn around. Oh, and it's in all the Pokemon Centres now. Yeah, that's a...lot of changed files.
