Fixed an error where SDCARDDETECTINVERTED was being defined/undefined
improperly

If the target temperature is changed then it would always stay in the reset state.
Thanks to @tonokip.

Replaces #2119

For sprintf_P() the first parameter has to be a `char*` not `const char*`.

replace extruder_multiply with extruder_multiplier
like feedrate_multiplier or volumetric_multiplier

- Use `setTargetedHotend` in `M200`, as with other commands that use
`T` for the extruder
- Synthesize the "invalid extruder" message, obviating several long
strings

To avoid double definitions.
I prefer to read N for Number not for Nozzle.

Was omitted when T0 is a MAX6675.

My PID_INTEGRAL_DRIVE_MAX was at 96, which was insufficient for my bed
to reach its intended temperature. The head requires a low maximum power since
I run on 24 volts and it has a somewhat low thermal mass.

to have it ready to display errors during (temperature)-setup.

- The command parser now displays “unknown command” in more cases.
Known commands must be added to the `switch` inside `process_commands`
to suppress the error.

REVERT THIS CHANGE

In proper use, we want to force the vendor to update this file to reflect distribution parameters

However, until most users have converted to automatic versioning,
we “grant them a pass”

And call _temp_error() directly for ERR_MAXTEMP_BED to avoid the only one time use of bed_max_temp_error().

Includes #2156.

to avoid stack overflow when called from interrupt.

Some clean up for calls of disable_all_heaters().
'disable_all_heaters()' is called in kill() and again when 'killed' is already set inside _temp_error().

- Affects code size when automatic bed leveling is enabled

!(~(ab)&0x3) and ab == 0x3 are equal

to warrant watching is set or reset.

Make setTargetBed() in _lcd_preheat() dependant of TEMP_SENSOR_BED.
Use disable_all_heaters() in lcd_cooldown() and abort_on_endstop_hit.
