According to LinuxCNC, G5 should throw an error if the current plane mode isn't XY.

* 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...

Fixes required for Creality CR-10

* 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.

Addressing #7552

When M405 is used it changes 'volumetric_multiplier[FILAMENT_SENSOR_EXTRUDER_NUM]' value. When M406 disables M405 it leaves the value unchanged.
This PR applies 'calculate_volumetric_multipliers' in M406 instead of resetting it to 1.0 because M200 may not be compatible with M405 hence I'm sure to restore anyway with correct value.

New feature: Part-Cooling Fan Multiplexer

Code reduction with some configurations

#7528 fix

There was a tab instead of spaces

When switching noozle and extruder but these operations are done by the same servo in 'setup' function there is a unnecessary call

I made an error in previous fix

#7504 integration has missed this part.
When more than 1 servo is used with bltouch it's impossible to predefine default servo delay for it.
In my original fix I completely removed this part but maybe this is a better compromise

Add Anet 1.0 to Platformio.ini

AutoParking Extruder (APE)

Followup to #7512

Individual servo delays

Fix for G26 spam output

Added env:anet10 to platformio.ini for easy compile and upload to this board

Add "Level Corners" menu item

* UBL_Language_Update

Translatable strings

* Use slightly better wording...

* Use slightly better wording...

* Disallow filament change while paused

* Use kinematic movemements in pause_print and resume_print

Correcting the storage selection.
Also EEPROM error handling on the LCD.

while heating, G26 will continuously spam the heater states instead of printing it out every 5000ms.

* work around previous regressions...

Prevent damage if DELTA_HEIGHT is set badly

This modify give SERVO_DELAY x servo basis

Miscellaneous style tweaks
