recall: support pgp/mime messages

Browse source 
PGP/MIME messages are stored encrypted and/or signed in the draft folder
for security reasons. Recall will open them through the lib.MessageView
interface in order to display the message content properly in the
composer tab. If the stored message was encrypted or signed, the
recalled message in the composer will also be encrypted or signed.
