Added volts+tenths and 8-bar battery check styles.

Reworked how voltage definitions work, and added one for each tenth of a volt.
Set default calibration for RMM attiny25V driver.
Made battcheck.py output all tenths in a wide range.
Changed bistro to use x**3 curve for better mode spacing.
Changed bistro's blink() to be compatible with volts+tenths code.
Tried to fit volts_tenths into blf-a6 for attiny13a but failed.
Made blf-a6 compatible with 8-bar battery check style.
