App 2.38.0: Overview styles Visor and Empire

Visor, after Halo's helmet display: the battery as the shield bar, the
range as the ammunition counter, P R N D as grenade slots, the speed in
the reticle with power round it, and the power trail as blips on a
motion tracker that sweeps while moving. Original blue or the accent.

Empire, after Age of Empires: a wooden resource bar, an isometric world
that moves with the speed, the car as the selected unit, P R N D as
commands, a diamond minimap, and ages by odometer (EmpireAge, tested).
The app takes the player's blue.
