Grapple target is visible even when disabled

[Malcolmnixon]

When the grapple movement provider is disabled (by setting enabled=false) the grapple target still becomes visible when aimed at a suitable layer. The problem is in the _process function of Function_Grapple_movement.gd. Specifically:

	# Update grapple target
	if !is_active and _grapple_raycast.is_colliding():

should be:

	# Update grapple target
	if enabled and !is_active and _grapple_raycast.is_colliding():

Grapple target now hides when the target can't be grappled.
