[Mailman-Developers] Quoted printable umlaut quick hack

I'm running mailman 1.1 on our intranet web server.

Since our lists are in German language, umlauts occure
quite often in mail bodies and subjects:   .
Depending on the used MUA these are often encoded
as quoted printables and end up as ugly trash in the
pipermail HTML archives: F=FCr instead of Fr ...
Unfortunately this dooes not only look ugly but also
prevents HTdig (the search engine) to find any words with
umlauts in the pipermail archives.  

So today I did some quick hacks to HyperArch.py which at
least work for me.  (Spend too much time on this detail already)
My dirty patch against HyperArch.py is appended below.
May be this will help somebody to do this right.

Regards, Peter
