added partial websocket support...
 - game id echoed back to page via websocket
 - other player notified when 2nd player is found
 - 'ready to play' button shown when all players present
 
 temporary functionality...
 - questions sent via http instead of websockets (based on when ready
submit is pressed rather than when last ready submission received)
 - different questions may be sent...function of 1st problem.
