Collin Kidder / GEVCU6 - History

Addition of PWM and slow PWM to digital outputs. Slow PWM does PWM
manually but allows for very slow PWM which is useful for things like
pumps and Tesla heaters which want 5hz PWM.

Removed some old files that weren't updated in ages and no longer
relevant

Add Tesla Battery Manager, a lot of misc coding style changes and
formatting.

Added a new device that tracks gear position with a potentiometer

Fixes to C300 code to allow support for two different comm schemes,
addition of code to support Ovar Charger/DCDC. Should also work fine
with TCCH chargers.

More work on C300 controller. It compiles now and probably nearly works.

Add a new inverter (not done yet but hooked into the system), fix
several compile time warnings, increment version number.
