Let's eat some dog food!

This was only intended as a quick POC, but perhaps it can be a starting point for working out what this should look like. I've heard some rumblings about a possible Typesafe site template. If such a thing exists, it should probably be added, as well. Also, the doc used for the Sphinx site is just README.md translated to RST via [Pandoc](http://johnmacfarlane.net/pandoc/).

I don't necessarily suggest this be merged as it stands, but wanted to open up this PR to get feedback on what else should go in here, if anything. At the least, one possibility would be to split up the contents of the README into separate pages. Also, it might make sense to change the README to just point to the site (and to add sbt-ghpages support so that it gets published as needed).

Thoughts?
