Added script/conditional chapter.

Also moved the script tags into a shortcode at the bottom of the
document, so as not to be a total hypocrite about where I tell
people to load things.

Removed the "serve" action from grunt.js, since it's not really
necessary for the way I'm loading files.

Added Google Code syntax highlighting (remote for now).
Decided to commit more. Added TOC.
Added the conditional page (thought I had added this before?)
