Title: Footnote support

[Redcarpet](https://github.com/vmg/redcarpet) and other markdown implementations have [recently added support](https://github.com/vmg/redcarpet/pull/271) for [PHP-markdown footnotes](http://michelf.ca/projects/php-markdown/extra/#footnotes)

This PR simply adds support for highlighting of footnotes.

Thanks
