QP Chisel Tools Exploit Fixes

Requires QP's Chisel Tools 

Fixes some of the more popular dupes:

• True Chisel and QP Chisels adding a new material to a block without consuming it. The block was only taken from your inventory client-side, so you were given back the block you used after you changed slots.
• Pantograph Undo duping chiseled blocks by breaking the block and undoing onto something else. Undo now requires claim access, cannot bring back materials the block does not already have and each save can only be undone once.
• Path Maker, Ladder Maker and Pantograph copy bypassing copy protection on blocks locked by someone else.
• Making a door and breaking it back into a chiseled block now use the server's own block data instead of whatever the client sends. Breaking a door also no longer removes the block's material limit.
• Block Swapper now only works in creative, since it placed blocks without consuming them.
• Blocked a network message ("pastenet") that let a modded client overwrite any chiseled block in the world. Nothing in QP's Chisel Tools actually sends it.
