Added syntax highlighting for code snippets in the documentation.

This is using Prettify highlighter: http://code.google.com/p/google-code-prettify/

Added "threejs.css" for doing custom styling (if somebody would like to do this). See for example here:

http://google-code-prettify.googlecode.com/svn/trunk/styles/index.html
