Add more App-Prefs to iOS

[RaphaelWoude]

Since iOS 10 the private API was deprecated to open screens, but since ios 13.1 you are able to use App-Prefs again. We have tested this on iOS and seems to be working fine with root:general. A upload to apple shows that you are allowed to use it and your app will not be rejected.

Implement all setting screens for iOS with App-Prefs.
