For the moment, I'm going to remove Corpus.Message, and change
FileCorpus.FileMessage to inherit from message.Message instead.  As far
as I can see Corpus.Message and message.Message are trying to do much of
the same thing, anyway.

I'll leave msgs.Msg alone since it's only for testing.  I think that
mboxutils is much the same as the Outlook plugin, in that it one day
will use message.Message, but it's too much hassle for the moment.  Once
message.Message has the 'choke point' code, the gain should be worth the

I've done a quick change and pop3proxy seems to still work, but I'll
wait to check things in until after the alpha3 release I want to do on
Friday.  This will give others (hopefully including TimS) a chance to
correct my misunderstandings...

If I feel inspired I might start work on writing up a clear
message.Message API, but otherwise not :)
