App 2.43.4: the Halloween pumpkin's light follows the music

The bass from Android's audio analyser drives the glow and brightens the
carving on the beat, only while the style is on screen. Yellow and green and
the embers keep their meaning; without a signal, as with the radio, the light
stays as it was. Levels only. Tried on the emulator. Not tried on the car.
