Tutorials are now strongly ordered, as opposed to passively ordered

- You will only see one uncompleted course on the Tutorial level select at a time.
    - All subsequent stages will not be visible.
    - This actually doesn't apply if you've beaten all the basegame Tutorial courses, and then load custom ones, to avoid discouraging the creation of those.
- If you select the menu and any loaded Tutorial stage is not completed, that stage will be highlighted automatically.
    - Uses the same icon as the Grand Prix backup tracker
        - Partly because it's the same general concept, saving your progress between sessions and alerting you to incompletion
        - Partly so I didn't have to bother any asset creators for something more specialised
