Convert site to jekyll

[bcomnes]

This turned into a slightly bigger project than I anticipated. We (Aaron, Barnaby, others in IRC) had a conversation about turning this into a jekyll site so we had a little bit more control over the site generation process. This is what I came up with.

I copied the different versions of the README.md files into their own distinct version (0.1.md, 0.2.md), and made the decision to simplify the actual README.md to give a higher level description of the project only.

I created some site wide variables in the _config.yml file that helps make it easier to keep track of project links from one place and reduce DRY violations.

I created an index.html that auto populates to the latest version of the spec set in site.config.

I assumed this would be a more simple process, but I forgot all of the little nitty gritty details that jekyll requires, so don't hesitate to reject this on the basis of complexity.

Ack, should have squashed this.

Also, part of this would likely be to delete the other branches for now, and make the gh-pages branch the default branch.

What is this solving?
