Test what happens with Konqueror 3.5 against the blacklist

Konqueror 3.5 is not mentioned in recent compatibility decisions
https://lists.wikimedia.org/pipermail/wikitech-l/2014-August/077958.html
and should not be affected by the recent changes, but one 3.5.4
user reports problems on en.wikipedia.org since few days ago.

Konqueror 3.5 was released in 2006 and is more a contemporary of
Firefox 2 than of Firefox 3.5, though last in 3.5 series was released
on August 2008. http://www.kde.org/announcements/announce-3.5.10.php
Maybe it should be declared as grade C if it's really not currently
functioning.

Some vulnerabilities are known to CVE for 3.5.5, 3.5.7 and prior;
Secunia reports a moderately critical unpatched vulnerability.
