Started working on new GUI
First compilabel version of new GUI. still incomplete and infuctional.
Fixed layout-issues. But still not complete functional
Implmented Lobby (a bit of it). Now you can join a server. Chat still
not functional
Added last missing old-menu. Butr it still has some unsolved problems,
like random crashes. Could not figure out what happens.
Finished rework of GUI. Now is "usable". But still needs much love.
Added missing headers
