[In Progress] Solarized Style

I wanted to create a new style using the [solarized](http://ethanschoonover.com/solarized) color scheme.

The layout will be responsive and feature the file list (and file TOC) as a left side menu, which will be accessible on narrow devices using a technique like [Sidr](http://www.berriart.com/sidr/).

The fonts used are PT Sans and PT Mono by [ParaType](http://www.paratype.com/public/).
