Manc.js site converted to use Jekyll static site generator.

Hello! I've converted the mancjs site to use the [Jekyll](http://jekyllrb.com) static site generator. It should work with your existing setup, you just need to run the build command (detailed in the readme) and run the server.js file as you do now and it will look exactly as before!

Additions:
- RSS feed
- Generated sitemap
- Asset pipeline for CSS and JS
- Jekyllness (markdown, yeeeeeah)

Hope you find the changes of some use.
