* 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

* Fix G26 Circles...

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

- avr-gcc is more strict than the Arduino IDE, it seems.

- 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.

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.
