  19.     PURPOSE:
  20.         Display message part data (whether it be text, images, or whatever).  Decode as necessary.
  21.         Sets HTTP "Content-Type" header as appropriate, so that the browser will (hopefully) know
  22.         what to do with the data.
  23.     PRE-CONDITIONS:
  24.         $user - Session ID
  25.         $folder - Folder in which message to open is in
  26.         $id - Message ID (not UID)
  27.         $part - IMAP (or MIME?) part code to view.
