[PW] Expanded Cat Fur Colors

Adds 72 new selectable, breedable, and paint mode colors for cats. Comes with a png colorchart (with cat photo references) for selecting the exact hexes used in this mod, for artists.

If you distribute cats made with this mod, the receiver is NOT required to have this mod installed for their cat to maintain the color you designed, presuming it works identically to the horse color expansion mod.
