The create dialog now hands back the map and closes at once. The library
creates the strategy and pushes the same route the tiles use, so the editor
paints on the chosen map right away and loads inside itself, instead of
loading every provider first and then fading the view in. The navigator's
load-then-push helper had no other callers and is gone.
