Yay for collaboration!
Add missing author items
Add some notes and TODO
Bring back the standard region selection tool. Users can now choose which they want to use. /dwe -type [standard/extender]
Make the extender tool show the correct selection volume
Narrate the correct usage info when the player gets the region selection tool
Rename the tool to wand. There are many other tools that are going to use the tool command, let's keep the wand as wand.
Lowercase all permissions in the off chance that some permission plugins don't handle mixed casing somehow if that's even possible.
Change the "standard" wand type to "cuboid"
Inset and Outset region selection commands
Clean up duplicate code
Add a shift command
