Bug 9857: Did you mean? uses wrong punctuation in search links

The link changes the search links generated by the plugins
from an=authid to an:authid, as suggested by Jared on the
bug report.

- Turn on the AuthorityFile und ExplodedTerms  plugins
  for the OPAC from the "Did you mean" section of the
  administration module
- Search a term in your OPAC where one or several
  authorities exist.
  A last name or a place name might work well.
- Verify that there are suggestions displayed on top of
  your result list.
- Verify that the link created is something like:
  /cgi-bin/koha/opac-search.pl?q=an=14084
- Apply patch.
- Verify the link has changed a little and still works
  correctly:
  /cgi-bin/koha/opac-search.pl?q=an:14084
