Allow to populate bubbles with extra content

We do this by making the ::populate-popup signals a little more
flexible. They used to just accept a GtkMenu as argument, now
they can take a menu or a toolbar. To not break the expectations
of existing callbacks, we only emit ::populate-popup with a toolbar
if the :populate-toolbar property is TRUE.
