Crash after 30 seconds of lag

[elexis]

If you host a game and your computer freezes for more than 30 seconds for some reason (like sunken boat lag on a18), the game will end for all players.

This is due to a default timeout value of 30 seconds in enet ( ​http://enet.bespin.org/ ) and once the local client / host disconnects, it's over.

We should disable it / set it to infinite for the local client / host:

// enet_peer_timeout(event.peer, 0, 0, 10000);

This issue has been reported in ticket:3264#comment:3. We should fix it here, so that we can decide on reasonable client timeout values in that ticket.
