Proposed improvement: change homing offsets to milimeters

Improvement suggestion:

Change:

#define DELTA_X_ENDSTOP_OFFSET_STEPS 0
#define DELTA_Y_ENDSTOP_OFFSET_STEPS 0
#define DELTA_Z_ENDSTOP_OFFSET_STEPS 0

to:

#define DELTA_X_ENDSTOP_OFFSET_STEPS 0.0*AXIS_STEPS_PER_MM
#define DELTA_Y_ENDSTOP_OFFSET_STEPS 0.0*AXIS_STEPS_PER_MM
#define DELTA_Z_ENDSTOP_OFFSET_STEPS 0.0*AXIS_STEPS_PER_MM

unless, of course, floats are an issue.

I'm not too familiar with the C syntax, but I'm assuming we will have to convert the number to an int before using it later in the code.

I can go ahead and open a git pull request, but thought it better to discuss first.

We need these values in steps as that is the unit we internally work for this correction. These get set by firmware with G132 S2 command during bed calibration so units should not really matter.

Yep. Well, until someone like me changes the microstepping rate and gets a head into bed crash spinning smiley sticking its tongue out
