Swap which characters share palette

It doesn't change any palettes. It just allows you to change all the standard character's palettes from one list.

Its also A lot easier than editing the OAM data required to get that changed palette to show up on the load menu, shops, and pretty sure roster selection. When you change the sprite, and palette, you'll have to change the battle palette anyway (also pretty sure FF3usME and others do it with a button).

It really is a nice bit of code.
