Earz version 5.3.6

We have again made some small, but still useful, improvements to Earz.

The teachers’ page:
• In the Student Tracking System, it is now also possible to filter by level within a given game.
• In the Livescore, the teacher can now also sort by % played.
• Within a folder, it is now possible (using a button) to (de)activate all games at once.
The app:
In settings, the transpose function has been extended: now per half note (max 2 octaves up and 2 octaves down).
