Fix 0.9.18 desync: CreateNetGame() slot creates signal-slot connections from hwnet to hwgame. The problem is that this slot is called asynchronously using queued connection, and hwnet could send some signals to hwgame before hwgame object is created and connected. Changed this to direct connection. Also changed connections to hwgame object to queued, but this is unrelated. Sorry, it is frontend patch. Maybe a little delay on server side could help, but not much, as tcp packets could get glued on client's side, and that greately depends on pc and internet connection performance. Frontend should be reworked to be safe for queued connections, as it is extemely dangerous to have a mix of queued/direct connections.
