Changes to widget-to-component branch in preparations of new 0.9 release

* Fix typo in .bowerrc
* Update .gitignorefile to ignore app/bower_components
* Update  array in package.json to valid JSON. This fixes npm install. Also this commit updates grunt and node versions.
* Update path to bower_components/aura/lib/aura in app.js. This will take in effect once 0.9 branch is merged in master of main aurajs repo.
* Update jquery to ~1.10.x in bower.json so we're using the latest and most stable version.
