Title: Add leaf decay preservation option.

As suggested by PilzAdam, nodes with a leaf decay rating of one will function as before, but nodes with a leaf decay rating of two will drop the decayed node.

As discussed at http://forum.minetest.net/viewtopic.php?pid=80182#p80182 , this could be used for apple decay.
