fix floating decomposing leaves.

Browse source 
leaves will now, upon beginning decomposition, check if there are
decomposing leaves on top of them which can fall down onto them. this
fixes an error where this situation would leave the top leaves visually
floating over the bottom leaves, even when there was space for them to
stack.
