qt: Allow setting the file name of signed and encrypted data
* lang/qt/src/Makefile.am (qgpgme_sources): Add signencryptjob.cpp. * lang/qt/src/signencryptjob.cpp: New. * lang/qt/src/signencryptjob.h (class SignEncryptJob): Add member functions setFileName, fileName. * lang/qt/src/qgpgmesignencryptjob.cpp (sign_encrypt): Set file name of input. (sign_encrypt_qba, QGpgMESignEncryptJob::exec, QGpgMESignEncryptJob::start): Pass file name to sign_encrypt resp. sign_encrypt_qba.
This makes it possible to store the original name of a signed and
encrypted file in the resulting data.
