prevent iOS gestures for going forward / backward in history

[ChristianMayer]

When using an iOS device you can go backward and forward in history by swiping right or left.
This can be very annoying with a CV page where you have sliders to slide horizontal and scroll the overall page vertical.

We should try to prevent that behavior as the CV is an application that doesn't need easy moving through the history.
(Note: a swipe to the right might be used instead to go one page upward and a swipe left to the last subpage when we were just coming from there; so we might be able to resure the iOS feature by just customising the behaviour by some history tricks)
