(svn r1108) -Fix: [Network] Fixed problem around slow clients:

They joined, they got the map, but it took some time before the new 
player was created. In this time a player could do stuff, causing a 
player-id-mismatch, and the player was kicked out. Now a player get's a 
nice GUI which says: registering.. When that is gone, the player is 
joined and can play safely. Tnx to Moriarty for bugging me with this bug ;)
