Tool efficiency aka automatic tool picker
Allows for picking the best tool to destroy a block automatically.
You hit stone? It picks a corresponding pickaxe. You hit dirt? It picks a corresponding shovel.
Toogleable via /te [on|off] or /toolefficiency [on|off]
Won't interfere if you want to use a specific matching tool. It will only swap if what you hold is bullshit and is indeed a tool (axe/pickaxe/shovel).
