RLG-Web: improvements to choices and status messaging.

Server-side, have gamemux 'end' events include the name and game, so
they can be sent to WebSockets connected to /status.  This means a
WebSocket client only needs to update its choice list when it gets a
begin or end message with its own username.  So it only needs to check
/pstatus/<name> at those times and can stop polling.
