Option for klipper only: Adjustment of "accel_to_decel" (#220)

* Klipper option: Adjustment of "accel_to_decel"

Add option to automatically adjust accel_to_decel to 50% of chosen acceleration.

* allow variable accel_to_decel percentage

allow variable accel_to_decel percentage for klipper firmware
