Freeze!

Hi Folks.

We had reports flooding in of crashes and the game just freezing up.
Managed to solve most of the hard crashes, but we have not located the freeze error yet.
To catch this error, i added a watchdog thread that checks regularly if the game is still alive. If it does not detect a life sign, it will crash the game. (giving us more info.)

More fun changes are coming, we are working on making joining/hosting networked games a bit easier and smoother.
