- The status screen uses the ST7920 character generator to greatly
  reduce SPI traffic and MCU load when updating the status screen.

- Has been tested with the RepRapDiscount Full Graphics Smart Controller
  but should work with any LCD that uses an ST7920 or fully compatible
  controller.

[2.0.x] Option to force homing of a dependent axis

* VIKI2 & RE_ARM changes

1. Remove `DISABLED(SDSUPPORT)` from ST7565 in `ultralcd_impl_DOGM.h`. These LCDs share pins with the SD card and can run at the SD card rates.

2. Add SDSS definition to `pins_RAMPS_RE_ARM.h`.  Apparently the SDSS definition in `pins.h` is being processed before the one in `spi_pins.h` which resulted in not being able to read the SD card.

[2.0.x] Allow M73 without SDSUPPORT

[2.0.x][Language] Update Czech (Advanced pause...)

`ENABLED` only works for flag-type options. Floats must use `#ifdef`.

Easier to configure. Catch an odd divisor.

[2.0.x] Improved CONTROLLER_FAN_PIN example in Configuration_adv.h

[2.0.x] Add delays to AVR driver for RRD Full Graphic Smart Controller

There is significant downside to breaking up the long line segments on UBL Cartesian machines.   It adds a lot of extra computation but worse...  It cuts out all of UBL's off mesh Z-Height correction checks.    There have been a large number of people complaining about the nozzle going to infinity or crashing into the bed lately.   They are being caused by
```
void unified_bed_leveling::line_to_destination_cartesian()
```
not watching over the segments being queued up for movement.
