Major: Now using css normalization instead of css reset + building up default styles

We're pulling in http://github.com/necolas/normalize.css/ developed by Nicolas Gallagher along with Jonathan Neal.

normalize.css retains useful browser defaults and includes several common fixes to improve cross-browser (desktop and mobile) styling consistency.

Lots of research has gone into normalize, verifying what are the default user agent styles provided by each browser. We can very specifically change only the ones we need to instead of the bulldozer approach.

Why this is great news:

* Who likes being so damn redudant and declaring: em, i { font-style: italic; }
* By using normalization instead of a reset + building up default styles, we use less styles and save bytes
* Less noise in your dev tools: when debugging, you don't have to trawl through every reset selector to reach the actual style that is causing the issue.
* More details here: http://necolas.github.com/normalize.css/

We're really happy to get user feedback on this, as we think style normalization is a better direction than resetting; and want to make sure you do too. :) Leave a comment here or in the Google Group: http://h5bp.com/group
