The app list view already skips events during overview, but this is not
enough because the app list window still consumes the tap event, and
then gets activating, exiting overview. Its ok now as we'd want to exit
overview anyways, but we're introducing side scrolling soon, so we need
the tap down event to not exit overview.

SearchBox view now does not need to check if we are in overview anymore,
since searchbox widget is a child of AppList window.
