Title: Fix dispenser duplication bug

When updating to 1.3.1, the dispenser was changed so that whenever it was powered by redstone, it would eject the entire ItemStack out of it instead of just ejecting one item.

The ItemStack inside the dispenser would be split by one as usual, meaning that you could keep firing the total stack out of the dispenser up until the stack inside the dispenser actually reached zero.
