Refactory code of MBScene.updateUI() from MBScene.show()

 - It is too busy to reborn full GUI components of pyink everytime the
   content being updated.

 - It is fixed by moveing code about updating of frameline to
   MBScene._updateUI() and avoid calling MBScene.show() to reduce time
   for updating frameline.
