[PATCH] cooked headers did rfc2047-decode everything which looked like an encoded word

the untested patch below fixes the article display.

tin still wrongly encodes some headers (i.e. if a Message-ID looks like an
encoded word tin will encode it once again to keep it's original format
instead of skipping References and the like when encoding an article) -> we
have todo something like this in rfc2047.c:rfc1522_do_encode().
