Villagers:

getProfession() -> Enum (what trade category the villager offers)

getType() -> Enum (based on biome villager is from; affects mob appearance)

Zombie Villagers:

getVillagerProfession() -> Enum

getVillagerType -> Enum   // MISSING: This is what I would like to see added.

I think this is a pretty reasonable request, since this is a basic villager entity trait.

Yay less reflection!
