Horse color-pattern variants

[EvModder]

Right now we have: BLACK, BROWN, CHESTNUT, CREAMY, DARK_BROWN, GRAY, and WHITE horse head variants.
However, horses also have a "Pattern" which combined with their color results in the actual horse appearance.

The available patterns are: BLACK_DOTS, WHITE_DOTS, WHITE, WHITEFIELD, and NONE.
This bug is for tracking getting heads for every combination of color + pattern

Does this impact the head?

[EvModder]

Yes, although some combinations are not very obvious impact
