Minor improvements

Things I usually do after starting a new project with Bones, and I'd love to see them included in the master.

- Loading jQuery in HTML5BP fashion.
- Cleaned up comments & JS enqueueing
- A better wp_title()
- GA Universal Analytics
- Responsive JS via [enquire.js](https://github.com/WickyNilliams/enquire.js)
    - Loading matchmedia polyfill via Modernizr for dumb browser (IE 6 - 8)
