NHF – new heroes for Heroes V 3.1.

Regarding Grol, maybe we could base him on (skeleton and animation) the Barbarian hero? Replace the head with Agrael's helmet, recolored to black; recolor the axe to black or change it to another one, so it resembles the axe from the artwork; as for the bull, I don't know what to do, but here are some options: try to have the hero ride, for example, a hell steed/nether horse or a hell hound/fire hound as an effect if it's not possible to fully attach it to the bull's skeleton. Another option is to make the bull look like a hellhound from Warcraft III.
