Allow enabling sand duping (#10191) 
Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable.

It should be noted that this decision does not promise all future exploits will be configurable.

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.
