qt: Allow refreshing a list of keys
* lang/qt/src/refreshkeysjob.h (class RefreshKeysJob): Add pure virtual member function start taking a list of keys. * lang/qt/src/qgpgmerefreshsmimekeysjob.h, lang/qt/src/qgpgmerefreshsmimekeysjob.cpp (class QGpgMERefreshSMIMEKeysJob): Implement new member function.
The new overload makes it easier to refresh some keys if one does
already have Keys.
