Track window shown state

Browse source 
Use a flag to determine whether the window is currently shown.

This replaces the old has_video_window flag, which was true only when
the window was shown and video was enabled.

This will simplify displaying a "disconnected" icon on device
disconnection when the window is currently shown.
