Found a CSS typo, switched to protocol relative URLs and removed extraneous files

As suggested by meecrobe in #14 pull request, the font URLs should be protocol relative. His change was to the rendered CSS file, I made that change in the SASS file.

Also, I saw a typo in the video that changed the font-weight on the blurb class. And then, I removed an invalid property that was used for a quick test.

And lastly, I removed a couple files that aren't used any longer.
