Move ownership of SceneOverlays to LayoutManager 

This patch moves the ownership of SceneOverlays from individual Layouts
to the LayoutManager. Deciding whether an overlay should be shown can
be done at the feature level rather than depending on the LayoutManager
to sort them. For the most part, this patch is a logic move, but checks
for whether an overlay is showing have been added before calling their
respective methods.
