also isActiveObject check moved to WorldObject - all worldobjects are inactive by default, excluding players this is a final part of cameras implementation (based on commit efc9623) Signed-off-by: VladimirMangos <vladimir@getmangos.com> Also remove template-way code selection for object for Map::AddToActive/Map::RemoveFromActive. This simplify function use from not Map code.
