Launcher mode: Gearslip as the home screen of a head unit or a dash tablet

Turned on under Settings > Connection, Gearslip's car screen fills the device's own
display as its home app. An All apps page opens any other app full screen, Back and
a head unit's keys work the car UI, and Phone hides on devices that can't call.
Phones never see Gearslip offered as a home app unless it's switched on.
