* 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

* [1.1.x] G33 magic numbers

* oops

* comments

* oops

* warning

* better comment section

* remarks

* extra grids

* auto tune calibration parameters

* solve warnings

* Tweaks to formatting

* review Thinkyhead

* Error

* 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

[1.1.x] Fix EndStops don't work with BOARD_RAMPS_14_EFB on Micromake C1

Based on #7637 by @marcio-ao

+Add French language without accent for japanese LCD

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

As pointed out in #7692 by @totalitarian

Forgot to update examples configurations. Done now

Ideally, it should be calculated based on Z steps per unit so that each
babystep corresponds to around 0.025mm. Smaller than this is largely
insignificant for typical layer heights.

* 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...

* Add Max7219 LED Matrix Debug Support

The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.

The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.

* Try to keep Makefile up to date.
