Removed the last vestiges of the object "layer". Scenes now simply have a

list of objects, they can overlap (I think that objects added to a scene
later will be rendered before objects added earlier which ends up feeling
natural in the editor); no longer are objects ignored when their footprint
lies outside the scene bounds.
