Disable the back button because the back stack behavior is confusing.
Instead of going back to the screen the user previously saw, pressing
back in enrolling screen goes back to FindSensor.

Show a skip button during enrolling in case the user entered the flow
accidentally. The skip button will send the result code RESULT_SKIP,
which is equal to RESULT_FIRST_USER + 1, back to the starting
activity.

Make a subclass for each enrolling screen that setup wizard uses, and
in override the corresponding get*Intent methods to always use the
setup wizard versions of the next screens.
On minor change made to the original flow is that it will now return
RESULT_OK if it is finished, as opposed to RESULT_CANCELED.
