Controls whether gravity affects this rigidbody.

If set to false the rigidbody will behave as in outer space.

	// Disables gravity on all rigid bodies entering this collider.
	function OnTriggerEnter (other : Collider) {
		if (other.attachedRigidbody) {
			other.attachedRigidbody.useGravity = false;
		}
	}
	// Turn this collider into a trigger on startup
	collider.isTrigger = true;
