Start fixing S/MIME
* src/cryptcontroller.h (m_bodyInput): Place to cache the plain text body. * src/cryptcontroller.cpp (CryptController::collect_data): Collect body into special data variable. (CryptController::lookup_fingerprints), (CryptController::parse_output), (CryptController::resolve_keys): Basically handle S/MIME.
We now collect the body of a mail twice because when we
do the protocol selection later we do not know if
we can do inline (S/MIME inline is not supported by us).
