Bootflat Update

Differences are barely noticeable. Mostly color tint changes.

I also added Font Awesome and I am using their AJAX spin icon.

The new version of Bootflat uses Sass, which is nice. I have already tweaked a few things and I would eventually like to port the project's existing CSS over to Sass.
