Improve error handling on encryption
* src/cryptcontroller.cpp (CryptController::parse_output): Handle the case the the user selects no encryption recipients. (CryptController::do_crypto): Accept error as argument and set it / use it. * src/mail.cpp (do_crypt): Handle error.
We still get General Error and Unknown Error way too much
but maybe it helps a bit. At least it won't give us
a little bit more information and don't show the bug
message.
