Calibration Consistency - Sketch 6.7.1

Some issues with calibration consistency were brought to my attention.

The debounce timer I implemented a couple of revisions back was likely pulsing the motors during the entire 3 ms debounce window. I've updated the calibration debounce logic as well as the distance and timing on the double press.

If you have had any issues please upload sketch 6.7.1 from the MK4 downloads page (please continue to use the 6.7 exe file - no update on the exe, only the sketch).

Please keep me posted as soon as possible with any and all feedback on this issue. Thank you.
