WebRTC File sharing peer2peer

Once websocket negotiation are completed, WebRTC and HTML5 File API are used in conjunction to allow file transfer between the users physical machines. Limitations:

    1. (Chrome) - seems to only work on small files 18k worked..
    50k files failed. On firefox tested as far as 2MB files all good.

    2. Only chrome -> chrome OR Firefox -> Firefox. 
    Can not send from FF to Chrome and vice versa.. read here:
