NPC Spawn Issue: decaying skeletons should be non-kos

[Estu]

I'd like to note that the skeletons in Dagnor's Cauldron don't behave like typical undead: they group aggro with water goblins and they start running at low health. Similarly, some weird stuff is going on in Unrest, where many of the undead (e.g. tormented dead) are threatening instead of scowling, and the death beetles (though they're not undead) never aggro you unless it's group aggro or you attack them even though they're threatening. I don't know how much of this is intended or correct; it just struck me as odd.
