Enable 6th-order jerk-controlled motion planning in real-time.
Only for 32bit MCUs. (AVR simply does not have enough processing power for this!)

This is an initial cut for feedback, updated for 2.0.x.

Chamber temperature is currently reported along with hot end and bed
temperatures to serial. The format is just like that used for hot end
and bed temperatures, but using 'C' prefix. As there is no heater,
target is always 0. Is this appropriate, is there a better way to report
chamber temperatures?

Chamber temperatures are not reported on the LCD in any way.

When auto chamber fan is enabled, it currently just uses the same
temperature threshold as the other auto controlled fans.

As the chamber temperature is not connected to any heater, it doesn't
undergo mintemp/maxtemp monitoring. This would need to change in the
future if chamber heating became a feature.

Some probes don't work near the edges of the bed. This change promotes MIN_PROBE_EDGE to a general setting that applies to all probing functions.

Some "fix-mounted" probes need manual stowing. And after probing some may prefer to raise or lower the nozzle. This restores an old option but tailors it to allow raise or lower as preferred.

With this option enabled, Z won't ever be raised until after `G28` has been completed, and it won't raise if Z becomes unknown. This is good for machines whose beds fall when Z is powered off.

- Also deleted old implementation files which had been renamed.

Implemented for LPC1768.

- 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.

Add compatibility with the original screen bord from Ultimaker 2 printer (UltiController v2.1 with the PG-2864ALBP I2C display)

Table is very very similar to old 104-GT2 so I added only the name and recycled old ID
