App 2.36.0: Overview style Grid, after the Tron films

Neon lines on black over a perspective grid floor that moves with the
speed; the battery as a light wall, power on a disc whose inner ring
turns with it, and the last two minutes of power as a light-cycle trail
of right angles (the Cockpit's PowerTrace, now in ClusterValues). Cyan,
or the accent colour; in cyan the app turns cyan too. In THEMES.md with
two screenshots. Emulator only; not tried on the car.
