Resolve #326 -- Server patience

[Killfrra]

• If the server's patience has run out:
  • If no one has connected, the server dies.
  • Otherwise, if there is at least one player who has confirmed readiness, the game starts.
  • Otherwise the server is waiting for someone to be ready to start the game, or for everyone to disconnect.
• If all players disconnect, the server dies.

Patience is set in the config as "forceStart" in seconds, zero to disable. 60 seconds in default GameInfo.json config.
