- Improve game_restart:

* differing screen resolutions and network settings are now honoured when changing fs_game
  * Fix hunk memory leak on game_restart
  * Move cls.state and cls.servername to clc so connection state is fully preserved over game_restart
  * Revert back to previous fs_game after disconnecting from a server that triggered a game_restart
  * Fix error dialog popping up after every game_restart if an error happened previously (reported by Ensiform)
- Fixed that not all commands added by CL_Init() would be removed by CL_Shutdown()
