REVISION SUMMARY
  Patch inlines the code of the constructor and destructor of the old
  QApplication subclass PolicyKitKDE and then reorders things as needed:
  
  - KDBusService for singleton run should be started before any further init
  - KLocalizedString::setApplicationDomain & i18n calls should be only done after the QApp instance has been created
  - KAboutData::setApplicationData best done before doing any D-Bus activity as that relies on app metadata
  - QCoreApplication::setOrganizationDomain duplicates app metadata setting from KAboutData::setApplicationData, only needed before due to latter done after first D-Bus activity
  - m_listener->deleteLater() in app destructor does not make sense, as the listener object is deleted due to being QObject child of the QApplication instance
