Subject: [PATCH] Do not highlight momentarily recalled scenes

Since momentary override is a singleton, it needs to remain
GUI only, and not a session API available to any UI.

The middle-clicked button is rendered as pressed. So it is
already obvious and the Changed() signal that is emitted
when temporarily restoring a scene can simply be ignored.
