With the introduction of the #if ENABLED(…)

reads better than

* Updates the auto bed leveling comments ONLY.
* Renames "Z probe" word usage in //comments and #errors properly.

* Fix a couple of renames omission and macro expansion errors.

Always end at [RIGHT_PROBE_BED_POSITION, BACK_PROBE_BED_POSITION]
Regardles the evennes of auto_bed_leveling_grid_points.

Use the shortest way between probing-points.

and use it.

Currently we use the probe exclusively as a device to find the build platform(bed).
For the currently supported setups this means, we use it as a additional min-endstop.
A triggered when not deployed probe disturbs the homing process for max-endstops.

Rename ENDSTOPPULLUP_ZPROBE to ENDSTOPPULLUP_ZMIN_PROBE
Rename Z_PROBE_ENDSTOP_INVERTING to Z_MIN_PROBE_ENDSTOP_INVERTING
Rename Z_PROBE_ENDSTOP to Z_MIN_PROBE_ENDSTOP
Rename DISABLE_Z_PROBE_ENDSTOP to DISABLE_Z_MIN_PROBE_ENDSTOP
Rename Z_PROBE_REPEATABILITY_TEST to Z_MIN_PROBE_REPEATABILITY_TEST
Rename Z_PROBE_ENDSTOP to Z_MIN_PROBE_ENDSTOP
Adjust comments accordingly
Remove Z_MAX  check for the probe in update_endstops().

Using an delta related idea of @clefranc from #61,
extended to the general change for all setups.

Tested with Prusa i3, max-z-endstop and permanently triggered z-probe.
Worked for @clefranc's delta.

Now all ramps configuration can enable Filament sensor not only EEB

If the printer is going to accept the M999,
then it should continue from that line number.

only X and Y were not implemented

PR#2572 Changed this because of faulty Boolean Logic

NOT(A OR (NOT B) OR (NOT C)) !=

(NOT A) AND ((NOT B) OR C))


Besides, the compiler should be smart enough to
optimize this without help from the programmer

This code is very EXPERIMENTAL and UNSUPPORTED
