* lang/cpp/src/Makefile.am, lang/qt/src/Makefile.am (AM_CPPFLAGS): Add suggest-override and zero-as-null-pointer-constant warnings. * lang/cpp/src/*, lang/qt/src/*: Consistenly use nullptr and override. -- This was especially important for the headers so that downstream users of GpgME++ or QGpgME do not get flooded by warnings if they have these warnings enabled. It also improves compiler errors/warnings in case of accidental mistakes.
