tone down the hyper-aggressive monkey ai

[Vitatroll]

Aw. Monkeys no longer follow my corpse around until they have somebody else to beat on. You guys are no fun. D:

For most people, though, I think how they are now is okay. They'll still kill you real well if they have cutting weapons. As a side note, giving a monkey treads and dual chainsaw arms worked out about as well as I expected. Though after a while he did stop using his arms because he somehow managed to mysteriously pick up some rods to hit me with. Boo.
