core: better back key (ESC) management:
- back key (which is mapped to esc keycode by SDL2 backend) is now handler with a platform
specific method when on root widget (i.e. a default widget is selected, or nothing is
selected). Default behaviour is to do nothing, while on Android the app is put to
background
- CagouWidget now has a default key_input method which go back to default widget.
