    Event Manager: Add window:deactivate and state-changed:active to spam clearers
    
    We use window:activate as an event to trigger event spam pruning during
    a flood. But window:deactivate should cover the situation where an
    inaccessible app (or no app at all) gains focus. And including state-
    changed:active for frames and windows is another fallback in case the
    expected window: events are completely absent.
