Polish and Play Store shenanigans

This time I had to update because of an Play Store requirement and took the advantage to add the fixes/features I've been working on.

- Google Play (Store) doesn't want links to websites allowing for Donations (Kenney Audio) so I removed it, thank goodness it's CC0.
- Feature: The Application now pauses when unfocused (it was draining battery like nuts since it's got a short timer)
- Bug Fix: Skip now hides the clone cursor (true/false). Skip away!
- Feature: Added Sound to some Tutorial actions
- Bug Fix: Combo is always saved (it wasn't on true/false)

There's more in store for this application but certainly not as critical as this.
