client websocket doesn't reconnect if server restarts

[rcmiller]

If:

• user opens Gitstream in their browser (making the websocket connection)
• server throws an exception
• forever restarts the server
  then the user no longer has an active websocket connection, so ./go.sh won't have any effect on the browser state.

Need to automatically reconnect if the server restarts, e.g. using cswac's techniques.
