Stash key headers when a message comes in: References/In-Reply-To,
Subject, Message-ID, etc. When a Web user reads a message or calls
for an index, the parent and followup data is at our fingertips,
so we can render a thread tree pretty cheaply.

I haven't worried a great deal about international charsets; I pulled
out some of the internationalization stuff from Mhonarc (mostly Perl
implementations of the ISO-8859-* charsets) and use that to render
the most common non-ASCII characters.
Right now we don't support non-text messages on the mailing lists,
so different MIME types are a non-issue for us.
