Refactory cod eof TweenObject.updateTweenContent and MBScene.setCurrentScene(). - updateTweenContent() use frameline.get_frame_blocks(), instead of frameline._keys, to get information of tweens and key frames. - MBScene.setCurrentScene() use 'ns0:duplicate-src' attribute to map nodes from a start scene to a stop scene.
