Added the new event S_EVENT_REMOVE_UNIT to trigger the removal of units (from groups also) when a :Destroy(false) or :Destroy() is called for a UNIT object.

The units are then removed from each SET that is subscribed to a set of UNIT objects or GROUP objects! Also the DATABASE is correctly managing this new removal method.
This to prevent the DATABASE getting corrupted with dead units, which were removed with :Destroy(), but which weren't cleaned from the database.
