Add  client JavaScript libraries to MVC sample. Fixes #22

This PR fixes client problem with MVC sample pages. The jQuery and Bootstrap client side JavaScript are required for implemented page features - including collapsible menu. So on small screens user is not able to access some page features.
This PR fixes this and uses CDN delivery similar to used in CSS delivery.
