Gtk: DnD extravaganza

- Correctly update drag status for drags over renderer. This makes things look quite a bit better.
- Rework the dnd utils so that we specify the drag targets in the order we prefer them (for destinations)
- Refactor code in bookmark bar so folder and toolbar drags share more code
- Allow bookmark bar to accept URI lists and plain text drags (for plain text we require the text to be a valid url)
