Enable loop for touch based navigation

[graup]

Thanks to #335 we can now have loops in the controls. That's great already.

However, when you display the controls all the time, the user might also expect touch swipe navigation to work the same way.

So it would be great if we could "swipe left" on the first slide which would jump us to the last slide. Not sure how that's possible, though.
