Add server-side timeouts for idle sessions

[Google Code Exporter]

The cube server needs to detect when a client has been inactive for too long 
and do a 'quit' transition for that client.

Server side timeouts are now implemented.  Inactivity (no client commands or 
faceclicks) on a particular client for more than 125 seconds automatically 
generates a QUIT command for that client.
