changes code to code-blocks to make readme a little prettier
adds jade compilation to gulp

I'm thinking the best way to handle differences between dev
and production builds is to use jade for conditionals, and gulp
for compilation of both variants.
separates dev and prod builds, and removes them from the repo

Okay... I think I am finally done with the gulpfile.

As the readme states, gulp gets you the dev build, gulp deploy
gets you the production build.

This means hosting this just means copying the build/prod dir.
