refs #140 , adjust sample for DBus marshalling / unmarshalling in order to test "tupel-ized" classes

* Added further DBus tests
* Crossover from refs #85 , removed dependency from generator adaptor and XML files, as this will not work anymore in the future
* Removed from .pro DBUS_ADAPTORS , DBUS_INTERFACES, QDBUSXML2CPP_INTERFACE_HEADER_FLAGS , QDBUSXML2CPP_ADAPTOR_HEADER_FLAGS
* Added interface, as this will be no longer generated
* Removed samples no longer required, the sample no represents a framework to test DBus marshalling / unmarshalling
