Scale extruder motor current linearly with speed.
49% less heating when running at low speed and standstill, 4% more torque at maximum extrusion rate (15mm^3/s), 15% more torque in high speed movements (un/retractions).
StealthChop mode is used for low speeds (below 900mm/min)
spreadCycle is used above. Transition speed is well above maximum extrusion rate of 15mm^3/s (275mm/min) so mode transition is not expected to be visible on printed surface.
StealthChop is expected to improve printed surface quality (less artifacts).
Warning you can burn extruder motor if it is not the same impedance as original Prusa i3 Extruder stepper motor. There is no current feedback in low speed so lower impedance motor can be burned by over current.
Even there is no direct current feedback, there is no risk for original motor thermal runaway, as motor resistance increases with temperature, current decreases.
Standstill peak phase current is expected to be 500 mA and linearly increase with speed to 970 mA at 900mm/min where spreadCycle constant current regulation takes over and keeps peak current at 805 mA to maximum speed possible.
As motor heating increases with current squared, lowering low speed current from 700mA to 500mA decreases heating 49% in thate mode, where motor spends most of the time.
Enable E-motor cool mode in farm mode only (and experimental menu) - the experimental menu is visible AND the EEPROM_ECOOL variable has a value of the universal answer to all problems of the universe - i.e. two conditions must be met at the start of the FW to enable the E-cool mode. If the user enables the experimental menu, sets the E-cool mode and disables the menu afterwards, on the next start of the FW the E-cool mode will be DISABLED. This is still subject to discussion how much obscure (security through obscurity) we'd like this option to have .
Additional stuff:
* Add serial debug msg to verify if E-cool mode is on
* Avoid access to E-cool mode switch on machines without TMC2130
* Do not allow only M907 E in case of E-cool mode+warn the user on the serial line that the command was skipped

This change restores the minimum extruder height for filament purge
during M600 from the current 50mm back to 27mm from FW 3.9.
We do this by introducing a new option for unload_filament() to indicate
that the unload is part of an automatic swap, and in such cases avoid
raising more than absolutely necessary (this will _also_ come in handy
to avoid the extra purge in PR #2318 during M600).
A new define MIN_Z_FOR_SWAP is introduced for this purpose.
MIN_Z_FOR_UNLOAD is still used for manual lcd unload and for M702 and
hasn't been changed.
- remove the UI and related stuff to setting a farm number (the
communication protocol must remain intact)
- remove confirmation after print finished ("Print OK")
Both requests are highly welcome, since they allow for lowering the code
size by >1KB
PFW-963, PFW-927
- Changed DETECT_SUPERPINDA to SUPERPINDA_SUPPORT as on miniRAMo the thermistor readings below 30°C
aren't accurate egnough to determine if SUPERPINDA is connected or not
- Add LCD toggle menu Settings -> HW Setup -> SuperPINDA [Yes/No] to overwrite SuperPINDA detection
- If EEPROM_PINDA_TEMP_COMPENSTATION is empty = 0xff then detect SuperPINDA by checking thermistor
- If EEPROM_PINDA_TEMP_COMPENSTAION is 0 then forec enable for temperature compensation menues and functions
- If EEPROM_PINDA_TEMP_COMPENSATION is 1 then force disable for temperature compensation menues and functions
Factor-out MIN/MAXTEMP [BED/AMB] out of the error message, which is now
built at runtime instead.
Introduce two missing ultralcd functions lcd_setalertstatus and
lcd_updatestatus to handle regular strings.

Remove variable CrashDetectMenu. Read this state from EEPROM_CRASH_DET instead in bool lcd_crash_detect_enabled().
Rename crashdet_enable() to lcd_crash_detect_enable() and move it to ultralcd.cpp.
Rename crashdet_disable() to lcd_crash_detect_disable() and move it to ultralcd.cpp.
Rename lcd_crash_mode_set() to crash_mode_switch().
Remove forward function declarations from *.cpp file.
Saves 34B of FLASH and 2B of RAM.
