GET updates

Future versions of GuideGuide will no longer send anonymous data (see #69). Data collection was the only reason for having a dynamic site. Since I'm not a back-end developer and [Jekyll 2.0 has shipped](http://jekyllrb.com/news/2014/05/06/jekyll-turns-2-0-0/), I'd rather have guideguide.me as a static GitHub Pages site.

This sets up GuideGuide to check for updates from static `GET` requests.
