:moyai: Added a real-time Dashboard with Socket.io

Thought this project would be more fun/interesting with a real-time dashboard driven by socket.io.  

I created a new dashboard page that shows real-time connections and browsing activity.  Typically this would be in an admin-type area of the app.  

I know this clutters the example a bit so you may not want to accept this but it's pretty cool.  No worries if you don't want to merge it.
