Bleeding Golems

Mob 20105 and 26803 are lead golems who are affected by bleeding: A lead golem continues to bleed from its wounds. A lead golem's bleeding artery MUTILATES it! A lead golem has some small but disgusting cuts. I think we need some kind of check (mob material, maybe?) to see if this should be the case. I could, maybe, see a flesh golem bleeding...but an iron golem? Weird that all golems are keyed to have PART_HEART...
