Notify user if websocket connection is blocked

Well, after a bit of work I stumbled across something that had been forgotten by the collective unconscious of the team - we already had a way of notifying the user that websockets were blocked by the network.  We had just commented it out.  So, in my biggest "bang for the buck" commit, I give you websocket network failure detection ... and I did it all by deleting two characters.

@jessmartin and @MichaelVacirca could you review, please?
