Cole Robinson 014d1ef99b console: Cleanup and improve console menu handling 
- Rework the ConsolePages abstraction to carry the Gtk.Menu. makes
  it all less messy

- Make the console menu the single source of truth for console
  embeddability, and error message reporting

- Small misc cleanups here and there
