WORLDGUARD-2654 - Reported by Gus.Callaway

So far, worldguard has a mob-damage flag which allows users to deny or allow mobs to damage players in a region. I want to be able to do the reverse. There should be a flag that allows/denys players from hurting mobs. If they are a member/owner in the region they of course can hurt the mobs. This is important because many players bring animals into their homes for breeding, but then just find them dead after a player comes in and kills them all.
