qt: Support verification of detached signatures directly from files

* lang/qt/src/Makefile.am: Add new files.
* lang/qt/src/job.cpp (VerifyDetachedJob): Move definition of
constructor and destructor and inclusion of the moc file to the
corresponding .cpp file.
* lang/qt/src/verifydetachedjob.cpp: New.
* lang/qt/src/verifydetachedjob.h (VerifyDetachedJob): Add member
functions setSignatureFile, signatureFile, setSignedFile, signedFile.
* lang/qt/src/verifydetachedjob_p.h: New.
* lang/qt/src/qgpgmeverifydetachedjob.cpp (class
QGpgMEVerifyDetachedJobPrivate): New.
(QGpgMEVerifyDetachedJob::QGpgMEVerifyDetachedJob): Instantiate private
job class.
(verify_from_filename): New.

* lang/qt/tests/Makefile.am: Add new test program.
* lang/qt/tests/run-verifydetachedjob.cpp: New.

This makes it possible to tell gpg to read the input directly from the
specified files bypassing GpgME's Data IO when verifying a detached
signature.
