* lang/qt/src/Makefile.am:

--
The ShowErrorMessage calls were removed and are to be replaced
by error signals / error status which the UI should then handle.

This allowed to port away from KMessageBox and KLocalizedstring.

Additionally this removed the old process bases qgpgmeconfigdialog,
and GnuPGProcessBase. Classes using GnuPGProcessbase were changed
to KProcess api.

This is a first compiling version. API is subject to change to
resolve the split between base jobs and qgpgme classes.
