more footnote classes and hidden footnote text

[jurisdatum]

These are the changes requested by Tim in FCL-41. Footnote markup will now look like this:

<p>
  Some body text.
  <a id="fnref1" href="#fn1" class="judgment-body__footnote-reference">
    <span class="judgment__hidden"> (Footnote: </span>
    <sup>1</sup>
    <span class="judgment__hidden">)</span>
  </a>
</p>

and

<footer class="judgment-footer">
  <hr>
  <div>
    <p id="fn1" class="judgment-footer__footnote">
      <a href="#fnref1" class="judgment-footer__footnote-backlink">
        <span class="judgment__hidden"> (Footnote reference from: </span>
        <sup>1</sup>
        <span class="judgment__hidden">)</span>
      </a>
      Some footnote text.
    </p>
  </div>
  ...
</footer>

Fantastic, thanks @jurisdatum!

I'm off tomorrow, but @dragon-dxw is there any chance we could push this up to staging at some point on thursday? I can then ship the frontend changes and unblock the release.
