/*	Object: Drone Combat - Designed to handle use of drones in a defensive manner, including 
		Launching, Targeting, Attacking, and Recalling.
	I designed this for use with obj_Miner, so that we may use our barges to tank rats while
	our drones destroy them. This way, we really don't have to worry about our drones being
	popped nearly as much, if at all. Just make sure you have a good tank.
