This is an update that adds support for RFC 2231-based encoding of MIME attributes to the webmail server. This primarily modifies encoding of attachment filenames to include native filename character set and language. It's a relatively recent standard. Up until now sqwebmail used encoding based on RFC 2047, which is the encoding used for character sets in the subject, and addressing headers. But, it looks like that someone decided that it would be a good idea to use a completely different encoding mechanism for MIME attributes, such as attachment filenames, so there you go.

And, just to make things more interesting, the whole mess is not backwards-compatible. Meaning that -- for now -- mail clients that are not RFC 2231-aware will not be able to see the default attachment filenames from sqwebmail. I'll try to think of something to mitigate that to some degree; 20020921 is a trial baloon to evaluate how big of a mess this is going to be.
