Revert "Added hack to make the same message appear on nav bar and on a sentence."

This reverts commit 8760234a14fc4395fc9be821e0bfb0c0c42f9d4e, since it
is just a bug in the stylesheet which renders the bottom link on the
resulting HTML page.
Removed too aggressive rule.

The affected line was modified in 2008. I think Konqueror is most likely
better with dealing with affected tags by now. This actually fixes the
missing link to our Bugzilla page, which was there, but simply not
displayed due to the CSS rule.
Kudos to Marco Ciampa for pointing this out.
