Enable change the relative feedrate on a printing job in delta machines with UBL

[1.1.x] Different NEOPIXEL types

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>

[1.1.x] Remove legacy ADVANCE feature

[1.1.x] Segmented manual moves for kinematics

[1.1.x] Allow UBL G29 and G26 to build without a probe

[1.1.x] Add support for 4 new LCDs

- Original CR-10
- MKS Mini Display

* Auto-enable DISABLE_REDUCED_ACCURACY_WARNING if HOME_AFTER_DEACTIVATE enabled

If HOME_AFTER_DEACTIVATE, there is no need to warn on LCD since printer will home prior to starting print.  Saves 60 bytes PROGMEM.
add HD44780 too

* Reduce lines used

[1.1.x] Fix DUAL_X_CARRIAGE manual move

XON/XOFF changes

[1.1.x] Fix broken M600 resume_print

[1.1.x] Option to disallow motion before homing

Forgot to update examples configurations. Done now

Added new configuration to inhibit XYZ movements when home is not done

Expected behaviour: while (auto)extruding the new filament, the nozzle should not move. It should move (from filament replacement position to printing position) only after the user has confirmed the successful filament replacement and extrusion.

Actual behaviour: while (auto)extruding the new filament, the nozzle moves from filament replacement position back to printing position.
So the extrusion step is mixed with the movement required to go back to the printing position.

The provided code seems to be working but probably a better fix is required.
