Little improvements of the day

- GA tracking code is useless because you are using Universal Analytics anyway

- Modernizr wasn't used anywhere in your code except for Respond.js (media queries support for IE8). IE8 does not need this to properly render your site anyway.

- The browserhappy disclaimer (appears on IE6) is now useless bloat.

- Add conditional comment to load HTML5Shiv for IE8 (improves rendering of HTML5 elements).
