Get Websocket demo chat running in Ringo

ringo-websocket.js

/*
  to get websocket protocol running in ringojs, do the following:

    * copy jetty-websocket-7.*.jar into your classpath (e.g. lib/)
    * add the following line to your webapp's config.js module:
          exports.extensions = ["ringo-websocket"];
      with "ringo-websocket" being the module name of this file.
    * download the client script from this page:
           http://blogs.webtide.com/gregw/entry/jetty_websocket_server
      change the location to: 
           "ws://localhost:8080/websocket" 
      and serve it as static resource from your ringo webapp.
    * Load that page in a browser that supports Websockets

  changelog:
    2010-05-26: updated to ringo/httpserver changes in git master
