This is old change that was declined (#105), but unfortunately it is necessary.
If every ID is based on world names, than addon cannot process "/" in it. It mean that worlds cannot be put into different folders.
This change will fix it, but it is not completed.
In progress.
There does not exist converter, so old data is not usable with this version.
It looks like, exist plugins that keep capital letters in world names. That mean, it is not correct to lowercasing any id's.
To fix it, now, instead of lowercasing, challenges should be case insensitive.
Challenge now will not know their world, as it is not necessary.
Remove ICON type, as it is useless.
Rename Level to Other, as under it will be not only level things.
Rename slot to order, as it was weird that users could define slot but not order. Order is easier to understand and use.
ChallengesLevel now knows all their levels.
Each challenge level only will be for single world.
Rename some variables.
ChallengesPlayerData was just adapted with changes in challenges and level classes.
