Make LWC lag less with hoppers

Commented out the onMoveItem event handler (could just remove it and the
handleMoveItemEvent method). I see no reason to check if a hopper is
allowed to move items in and out of inventories when, by default,
players aren't allowed to place hoppers next to protections they can't
access. Just keep '154' in the blacklist and add 'hopper' to the list of
protectable blocks, and then trust the players and admins to not do
extremely stupid things.
