Start nav, kill some images, compress others

* Hack in a nav so that we can have a blog section
* Does nothing yet (no posts to draw from)
* Take out all the float stuff and re-order nav with push/pull
* Compress all the pngs with a tool
* Kill some unused icons
* Kill grunt-contrib-watch because its the crappiest
* Bring down Open Sans fonts and css locally
* Include google analytics directly
* Import github and solarized styling instead of concat
