[Patch] Prevent FilterSet::addFilter in khtml_filter.cpp from incorrectly parsing rules with options...

[Dawit A]

Hi,

The attached patch is intended to fix an issue in FilterSet::addFilter
where a wilcard rule with options, e.g. *$image,~image,donottrack, is
parsed as "*". This causes all urls to match this filter and cause
unintended side effects when adblocking is enabled. Note that the
above filter rule was obtained from
