Adds angular JS library and simplifies the page

Added the angularJS 1.2 (legacy) library via CDN call. Added controller javascript that will make the FBOpen call.

Simplified the main index.html page as well to remove some unnecessary flash and empty features which were slowing down the site or making it confusing.

Converted to using the ngResource for REST services and then added default query parameter (api_key) and added further filtering.
