Add hljs class to all code blocks, regardless of highlighting

Fixes #179.

Highlight.js does not apply syntax highlighting to code blocks marked
no-highlight, nohighlight, plain, or text. When it finds blocks of those
languages, it does not add the `hljs` class to those code blocks either.

highlight.css and tomorrow-night.css use the `hljs` class to give code
blocks their backrgound color and text color, and we want that to apply
even if the code doesn't get syntax highlighting markup.

This is a somewhat hacky solution to get just that behavior! After this
commit, code blocks with no-highlight, nohighlight, plain, or text
language set on them will indeed get the hljs colors.
