[UX] Implement hasFewKeys prototype (#6195)

Browse Source 
This is a quick exploration into how the new Device:hasFewKeys() method could work to make things more usable on very limited devices.

In the reader, the right is repurposed to open the menu. Left in turn closes it.

The same principle is applied to ButtonDialog. This means you can select anything in principle, but once you go right you can't go back.
