Ok, so i made the old master branch a dev branch for the network client.
And since i put this under the GPL3 after i added some network stuff i now
added the gpl stuff again. I haven't compiled it yet and need to fix it to use 
the new box2d and sfml libs.

Also there is a lot of refactoring waiting for me down the road.
And the persistence part needs a complete overhaul.
It's just too damn ugly.
