* Prevent crash at camera list update at attempt increment end() iterator.
* Properly do unapply SPELL_AURA_MOD_POSSESS_PET (GetPet() can return NULL at call, and not need checked)
* Propertly call unapply at delete auras cases for auras that set player-caster mover pointer.
also isActiveObject check moved to WorldObject - all worldobjects are inactive by default, excluding players
this is a final part of cameras implementation
