GTK: Cause the page-info popup to appear in the right place

To position the page-info window we have to tunnel all the
way from the current scaffolding, via its top-level gui window,
through to the toolbar.  In the toolbar we look up the URL bar
and then determine the screen coordinates of the scaffolding
via the top level widget GTK semantics.

Finally we place the page-info window 4 pixels down and right of
the bottom-left of the entry box, which should look nice.
