[General] ImageMorph Opacity & lively.scene.Group [Some Corrections]

ImageMorphs do not appear to support opacity. However SVG groups do. How do
I extend ImageMorph to nest lively.scene.Image inside an lively.scene.Group
to allow image opacity? How do I use lively.scene.Group to affect the
overall opacity of a set of child morphs?
The goal is to perform animated transitions: click on an image and it fades
to a Flickr/Google image results selector and then fades back.

Thanks,
Phil
