Enable pygments colorization
Switch to the Hyde layout from Poole

The Dinky theme works but it has a rather restrictive setup for adding
navigation to the site. Hyde fits better with what I'm looking for.
Explicitly set sort orders in the navigation

Double loop idea from
http://stackoverflow.com/questions/9053066/sorted-navigation-menu-with-jekyll-and-liquid

Github pages doesn't allow custom plugins so we have to work with liquid
directly and this was the best solution I could find. The code is
inlined to keep from generating a ton of whitespace in the final output.
