Subject: [PATCH] [staging] Double-clicking on stream row toggles its zoom
 level.

If you double-click on a stream that you've narrowed to, it
will either zoom in or zoom out the left sidebar view.  Zooming
in shows just that stream; zooming out shows all streams.

This is feature flagged to staging only.
