fix(app): add jQuery <script> into index.html template

Since jQuery is always included, regardless of answers from the prompt, I've included it in the `index.html` template. I also placed it before angular.js, allowing Angular to use jQuery, and not jqLite. The cdnify task then picks it up.

This helps solves issues like: http://pastebin.com/zxNQuVFR

I'm surprised this hasn't come up before, which makes me feel like I'm doing something silly.
