Minetest 0.4 Mod: Worldedit++
=============================
by PilzAdam

Descripton
----------
Worldedit++ adds commands to Minetest to easily set/modify thousands of nodes.
All commands require the "worldedit" privilege.
The commands are executed step by step, wich means that the server does not lag
at all if a Worldedit++ command is running. It is still 100% playable.
If a player starts a command it gets enqueued into the serverqueue, and it will
be started if the commands in front of it are finished. This makes it easy to
use on multiplayer servers.
Every player can only have one command at the same time, wich is either running,
waiting or paused. Position 1 & 2 and the selected node are also saved per
player. They can't be changed while a command is running, waiting or paused.
Currently supported commands are:
 - /wpp
    - no parameters
    - prints information about positions, nodes and commands
      of the player
 - /p#
    - optional parameter: <X>,<Y>,<Z>

    - sets position # for the player to the player position or x,y,z if
      specified

    - parameter: <X>,<Y>,<Z>
    - # is either 1, 2 or 3
