Subject: [PATCH] Fix inconsistencies in dispense events regarding stack size
The javadocs for BlockDispenseEvent suggest the ItemStack is a single
item which is being dispensed. Before this fix, sometimes it was the whole
stack before a single item had been taken. This fixes that so the stack size
is always 1.
