- added socket.io support to node.js server
- added public/angularjs and public/knockout, so they are (static) hosted on node.js => needed servertype 'node08' for this during deploy

=>  to test the application, http://ae-todo2.cloudfoundry.com/angularjs/index.html (multiple browsers for socket.io communication)
