Tim Culverhouse 6a10123f4a gpg: don't send messages that failed encryption
Add error handling for messages that were unable to be encrypted.
Previously, messages that failed encryption would be sent with no
content. This patch adds error handling - when encryption fails, the
user is returned to the Review screen and instructed to check the public
keys for their recipients.
