BowserBro palettes and slight Bowser file clean-up (#636)

* Different world palettes for BowserBro, and slight optimization to Bowser.

BowserBro still will not use Bowser's green palette in any of the areas where the game would genuinely use the green palette, but he will follow the rules of other non-green palette areas so he has more consistency in those areas.

* BowserBro palette and sprite now correctly set.

* Fix Bowser.png
