- Fixed a bug that would not disable the steppers if a user issues a system abort during a homing cycle. - Updated the hard limit interrupt to be more correct and to issue a shutdown for the right situations when the switch has been triggered. - Added a status message to indicate to the user what happened and what to do upon a hard limit trigger.
