  UIxMailPartMessageViewer

  Show message/rfc822 mail parts. Note that the IMAP4 server already returns a
  proper body structure of the message.

  Relevant body-info keys:
    to/sender/from/cc/bcc/in-reply-to/reply-to - array of addr-dicts
    type/subtype          - message/RFC822
    size
    subject
    parameterList         - dict (eg 'name')
    messageId     
    date
    encoding              - 7BIT
    bodyLines             - 83
    bodyId                - (empty string?)
    description           - (empty string?, content-description?)
    
    body                  - a body structure?
  
  Addr-Dict:
