New webarchiver plugin

[Matthias Grimrath]

Hi,

I have rewritten the webarchiver plugin and filed a "bug" report a 
while ago, please look at 
<https://bugs.kde.org/show_bug.cgi?id=98695>.

In the meantime I ported it to KDE 3.4.2. I am still happy to 
contribute the code, just tell me how to do it :-)

Greets,
Matthias
