First cut of highlighting code samples

Defines a new style that you *must* include in the @title() element of a
page that causes the right javascript and CSS to get loaded

Uses a version of highlight.js that has been slightly hacked to:

1) Look for .code-sample instead of "pre code" to find code to highlight
2) Auto-initialize itself at the end

Bug: Need to figure out how to *add on to* not override the default
style
