Switch to Precompiled Templates

And use lodash templates for Solarized.

This lets us get rid of the slow, uncompiled Jade and use the style's
compile method to create a self-sufficient JS module that use any
template language.

BTW, `require('jade')` took 400ms on my machine. Requiring `lodash`
takes 3ms.
