title: How could include javascript libraries on a wirecloud operator
body: <p>I am trying to develop a wirecloud operator but I don't know how to include a javascript library  (i.e. jquery) on the config.xml except the main.js file. I tried to include the jquery library on the config.xml just like the main.js way, using different wire:index, but it did not work. </p>
  
  <p>Is there any way to include a second JS library?</p>
