Styleguide

Here's an initial go at a styleguide. I opted for Yahoo's Pure framework as it is refreshing to work with, lightweight, easy to pick up and will allow us to move to mobile app someday. The biggest divergence from what we have now is the addition of a "white app menu" up top. We're based on a standard 960 width - and the Pure grid is then nested inside it. I figure we can add the 'app-y' controls in on the sidebar? Dunno, totally open to ideas and brainstorming.
