Registration of MIME media type application/sema

[ned.freed at mrochek.com]

This sure looks like it belongs in the vnd. tree to me. Please see the
rules regarding registrations in the IETF tree laid out in

  http://www.ietf.org/internet-drafts/draft-freed-mime-p4-04.txt

Sections 3.1.1, 3.2.6, and 3.2.9 seem particularly relevant.

> Secured eMail is a system for encrypting/decrypting email. It consists of
> two parts; The Secured eMail "writer" which is a pice of software which is
> installed on the senders computer and is used to encrypt email; and a
> "reader" which is installed at the recipients computer to enable decryption
> of the email. The first implementation of the "writer" is distributed as an
> add-in to Microsoft Outlook on the Win32 platform but other implementations
> will follow. The first implementation of the "reader" is distributed both as
> an Microsoft Outlook add-in and as a standalone Win32 executable for
> recipients who do not use Microsoft Outlook. When an email is encrypted, it
> is transformed into a document with encrypted binary data called a Secured
> eMail Archive file and this registration is intended to register this
> document format as a mime type.
