Draft: Address #68: Add syntax highlighting of examples to cmu-user
We add syntax highlighting of examples to cmu-user.
Syntax highlighting is done using highlight js and is set in docs/texi2html.init. This supports highlighting things in @lisp and @example. This works for Lisp. I think it should work for C as well, but currently doesn't. Also some @examples that contain mostly Lisp don't get highlighting. I'm not sure why.
Also, we add some CSS to add a background color to examples and to the nav panel to set these off from the surrounding text. This is modeled after the emacs manual.
