Implemented synchronization message output for NanoDLP printers (nanodlp.com).
If optional feature is enabled in `Configuration_adv.h`, Marlin will ouput "Z_move_comp" string to serial after completing any G0/G1 Z-axis movements. This feature patched on previous versions(1.0) is used by NanoDLP to synchronize Z-axis movement with projector exposure in DLP stereolithography printers.

Also...   Doing a 'Direct Commit' to see if that is 'acceptable' for small changes like this.   I want to look at the commit history and see how the logs handle this type of change.

* Fix thermal protection documentation.

Even before the recent thermal protection changes, the documentation of
the thermal protection feature in the config files did not match the
implementation.  I fixed the documentation and reconciled the M303
implementation with the documentation.

* Applied documentation changes to sample config files

* Renamed hysteresis to watch_temp_increase

* Added gcodes back into documentation.

* Fix G26's circle drawing...

This mostly catches the bugfix-v1.1.x branch up to bugfix-v2.0.0

I'll have to do something similar to get bugfix-v2.0.0 caught up to
bugfix-v1.1.x

* only use planner.leveling_active if appropriate

* Initial conflict resolution

All previous items resolved:
- Use of ELAPSED() on timer code
- Switch to use of defer_return_to_status=true as much as possible
- Update & Clean Up of Max7219 routines

* Resolve non-SD case in ultralcd.cpp

Based on #7637 by @marcio-ao

Changes to support NEOPIXEL LED strips
- Support for different NEOPIXEL as defined in Adafruit_NeoPixel.h
- ability to setup startup brightness
- ability to define sequential/non-sequential transition of color change during heating-up
- additional parameter to M150 P<brightness>

- Original CR-10
- MKS Mini Display

Forgot to update examples configurations. Done now

* Add MAX7219_DEBUG to Travis CI testing

* Tweak config and use standard pin naming for MAX7219_DEBUG

* MAX7219: Apply coding standards, use macros, etc.

* Make code work...
