Subject: [PATCH] Update excerpt helper to properly filter HTML footnotes

closes #4741
- updated regexp to properly filter out footnotes without removing too much text
- happened only when a link was used before a footnote
- old regexp was too 'greedy' and removed regular link together with the footnote
- new regexp uses a more specific <a> tag
