- Removed JavaScript like Modernizr and jQuery which we currently don't need
- Removed the HTML5 Boilerplate doc files
- Added new logo/favicon
- Added Roboto webfont
- Added .gitignore file to ignore some cfg/os files
- Combined normalize.css with the main stylesheet and minified them.
(Using SASS now)
