Balsa + Bcc messages

[Brian Stafford <brian stafford uklinux net>]

Hi Pawel & co.

I've redone the Bcc patch to apply to the current version of Balsa from CVS.

When a message has Bcc recipients, it creates the libESMTP message structure
twice.  One message is distributed to the To: and Cc: recipient list and the
Bcc: header is stripped by libESMTP.  This satisfies the requirement of not
revealing Bcc: recipients to the primary recipients of the message.

The second copy of the message is circulated to the Bcc: recipients only
and preserves the Bcc: header.

In the identities dialogue box, there is a field for Bcc:  I assume this
is intended to make a personal copy of all messages, i.e. like a file copy
but sent via the MSA.  This probably doesn't do the right thing any more.
Ideally this will add an extra recipient to the SMTP envelope of the Bcc:
copy of the message if present, otherwise it should add the extra recipient
to the To/Cc copy of the message.  It certainly should not be added to *any*
recipient header, especially not the Bcc: header since this would cause two
copies to be sent unnecessarily.  Just now, I'm not sure how to implement this.
Any pointers (or volunteers) gratefully received.

Other minor stuff.

When message submission fails, the error message refers to "delivery".  It
should refer to "submission".  I've changed the text to reflect this.
