Add style for markdown footnotes
We might want to consider styling with markdown footnotes. I can envision a thin line separator, maybe a slightly smaller font (like real footnotes). We might also consider a different backref icon (or I would even suggest not using an icon, just the actual unicode return `↩` character, which would be more subtle).
Once https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24168 is merged, we will have the proper classes wrapping the footnote elements:
1. The entire footnote section is wrapped in `<section class="footnotes">`
1. The back reference link has the `footnote-backref` class
1. The superscripted reference has the `footnot-ref` class
{width=50%}
