Feature/css3ify

Ok, so this is the cleanslate version you want! Sorry it took me so long to get it to it.

This resets CSS3 styles (the ones that you want to reset).

It also normalizes form elements as near as I could get them to a webkit appearance.

I also updated the targeted HTML5 tags to be up to date and be a bit future proof. There's no consequence to the tags not being being fully supported right now.

There's also a test document attached that I used to compare cleanslate elements to default styling. This is only for form elements.
