Subject: [PATCH] Basic UI: Signal resize of properties view

If the properties view changed in the properties window, the viewport of
the properties would not trigger a resize because the size of the window
itself does not change.  This creates a signal that allows the parent to
know whether or not to update a viewport, if any.
