Remote control working + clean up.
 Routes
  Sorted routes: clients to / and a controller page at /sausage
  So ip:port/ shows masonry grid; ip:port/sausage shows control page with button
 Websockets
  Clicking control page button removes image from masonry grid on every client
  socket.io sends message from sausage to server which broadcasts to all clients
  Clients listen for 'message' and remove image when it's received
 Cleanup
  Changed public/script.js to public/home_script.js
  Added public/sausage_script.js
  Added sausage directory with index.js and sausage.jade
