Skeleton: Added App Metadata.
Skeleton: Using Bower for Package Management

Installing app specific libraries using bower:
 * LeapJS
 * Bootstrap
 * JQuery

Setup Brunch to concatenate bower libraries into vender.js

Removed jquery 1.8.3 from the hardcoded vendor folder (It's being
managed by Bower now, and has since been updated to the latest
2.x version).
Skeleton: Upgrading UglifyJS Brunch

The version that comes with the skeleton (1.3.1) contained a buggy
version of UglifyJS which failed to minify the latest JQuery.

The current version (1.7.7) does not have the same issue.
