Disable motor coils while motor is stopped

[casainho]

Idle current draw (stock) is 80-90mA, new fw 130-140mA, no big deal.
New firmware applies resistance to being pushed backwards, stock firmware does not.

I think this is related, because that resistance means that motor coils are always energized while motor is stopped... still, the current on them should be 0 because they have the same voltage applied to them (Voltage battery / 2), slight imperfections on the circuit and/or coils, may result on the very small increase of current.
Anyway, I think would be better to have motor without resistance when pushing backwards.... happens that there is a tecnhical issue to make that, that I could not understand yet on how to do that with this motor controllers hardware: start the motor while it is running.
