Android: For the moment disable swiping to change notebook pages.
Horizontal swipes conflict with other drag motions we use on some pages in
dwtest... like the horizontal sliders. So disable it completely for now.
It is a nice feature though for notebooks without controls it conflicts
with. So might add it back later with a flag.
