Updating to socket 1.0 and Express 4

[forddyce]

Took a liberty of copying your code and make it run under socket.io ver 1 and express 4 located here: https://github.com/forddyce/programme-chameleon/tree/master/public/app

Was going to add download feature (I will add a table and when a user clicks on download button the

will export as xlsx and download, table created by room master and downloadable by participants). Also going to add feature on showing what room I'm currently at, and a "logout" button without the need of refreshing the page. Any ideas on the feature I mentioned?

@forddyce as soon as i type a message , I get "Cannot read property 'rooms' of undefined" and the server crashes.
