This is something of an experiment but now the app roll is traversed using
horizontal swipes and applications should primarily use vertical swipes
to navigate internally. This is mostly because if "feels" better but it
also leaves the vertical scrolling hardware available for use by the
app.
At this point both the simulator and a PineTime will come up
and show a clock (although in the case of the PineTime the clock
will just come up at 12:00).
