RLG-Web: delay removing TermSessions until the client is informed. Add a TermSession.sendq flag that indicates whether a type q message has been sent to the client. Don't immediately destroy the TermSession on child exit if the message hasn't been sent. This is an ugly hack until the TermSession class is separated into an EventEmitter to handle the PTY and a listening object that handles communication with the client. That will also allow other clients to watch the game.
