Make the PDF icon prettier

This script replaces the standard PDF icon with a nice Font Awesome version that matches the other Article action icons.

To use these, copy the relevant code at the very bottom of the Article template (if you're not sure how to do this, see here).

<script>
$(function() {
$('.hg-article-pdf img').replaceWith('<i class="fa fa-file-pdf-o"></i>');
});
</script>
