Subject: [PATCH] Mantis 60004 problems with damage and llSetDamage. In damage
 enabled areas this patch - Deletes any objects that have damage set > 0 that
 deliver that damage to an avatar Stops Gods receiving damage, Stops volume
 detect objects causing damage Deletes NPCS when their helth reduces to zero
 Gradually "heals" damage to an avatar Resets health on going to a non damage
 area
