styles.css: Minor cleanup.
Minify normalize.css and include it in styles.css.

This way we have 1 less request and save bytes. Until we have a proper deployment solution to minimize the files, this seems the best solution.
Update media queries.

Use what Bootstrap is using.
Add respond.min.js and selectivizr.min.js.

This makes media queries to work on IE < 9 and CSS3 features.
_layouts/default.html: Add keywords.
Add missing titles to pages and description to the index page.
Change page title.
Add README.md.
Merge pull request #9 from XhmikosR/master
