Copy itemstack when sanitizing for datawatcher items

Quellcode durchsuchen 
Since the packet is broadcasted for players, it means that
the packet will be sent to multiple players. In this case,
modifying the data results in a possible race condition
where a CME may occur as the packet will be serialized on
many different netty IO threads.
