Add `//tool`

Problem

We need a way for players to get WE/WEA wands without creative menu.

Solution

//givewand <id> (requiring worldedit and give permissions) will give the player the specified wand

Alternatives

I really don't want to make recipes and have them toggled by worlds settings so let's not even consider that. 😴

The normal WEA register command should do here. It can handle the permissions checks for you.
