fix: niveaus bij wereldoriëntatie nu als knoppenrij, net als de andere oefenwidgets (v0.4.19-beta)

- Bomen/vogels/planten/topografie verstopten "Niveau" als een los
  keuzeveld onderin het inklapbare Instellingen-paneel; de oefenklok,
  het geldwidget, plaatswaarde en rekenwidgets tonen niveau altijd als
  een knoppenrij bovenaan, direct zichtbaar tijdens het spelen.
- Niveau is nu overal dezelfde knoppenrij (Niveau 1/2/3, met uitleg per
  knop via title, net als bij de oefenklok) direct in de bovenbalk naast
  de score - geen Instellingen meer nodig om niveau te wisselen.
- Niveau wisselen zet score en reeks terug naar 0, zoals bij de andere
  oefenwidgets (voorheen bleef de score gewoon doorlopen).
- Topografie: de knoppenrij verdwijnt bij "Landsdelen", waar niveau toch
  al niet van toepassing was - zelfde gedrag als voorheen, nu alleen
  consistent met de rest.
