Actually fix plum trees dropping apple saplings (Only newly generated trees will be affected)
There are no fruit trees with 2x2 trunks.
Previously generated plum trees will now drop plum saplings (so long as they still have plum leaves)
Reverted change that would pop up a forge warning message for players who have worlds from before this patch.
