Incorporating the shared ptr code: - All scenegraph references from SimGear - SGMaterial which already had a reference counter uses now that common infrastructure. - SGMatModel is now counted. - SGSoundSample from SimGear - And the corresponding change for the sound samples in flightgear which fixes a latent crash if FGBeacon would evern be deleted.
