Tim Culverhouse 8f9bb2b289 pgp: fix pipe|open|save command behavior
Signed and/or encrypted PGP messages did not behave properly for pipe,
open, and save commands. Specifically, the proper Message Part would not
be passed to the command in the MessageViewer. This is due to the
encapsulation of the body structure. This patch fixes the behavior for
piping|opening|saving of message parts.
