Option to show four playback buttons in performance mode

This has been requested by a few customers.

With three playback buttons, it’s not possible to skip to the next song while you’re in a loop and playing. Having a fourth playback button, like in the setlist view, would make this easier.

This could be an option that can be enabled on a per-device basis.

I’ve just released AbleSet 2.5.0-beta.5 which supports this feature. Let me know how you like it!
