[sdk] Change "Back button" to simple right-swipe from the center of the screen.

[Alexander Nilsen]

Back button is located in left-upper corner.
Stretching the thumb to that corner is not easy (regardless left- or right-hand usage).
More natural will be using horisontal swipe from the middle of the screen, the same way as it's done for shuffling scopes back.
I think it will work almost everywhere, making interface experience more streamlined.

-------- UX comment -----------

While swiping left and right in the center of the screen for navigational purposes works for scopes, it would lead to issues in many other places.
As stated below, list items have the ability being swiped to the left and to the right, which would interfere with the navigation. An other example is the camera app, where user access their camera roll/last picture shot.

This is why the proposed interaction is not suitable navigating between applications.

[Zsombor Egri (zsombi)]

There is a slight problem with this, which is that ListItem elements handle these gestures to swipe in leading actions. If you do that above those, the page navigation won't be doable.

Marking as INVALID, please see UX comment in bug description.
