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