file

One list less to maintain.

  *firmware version / branch / date.
  *extruder count
  *board information (name, serial details, power supply type)
  *thermistors (names, min/max temperatures)
  *printer statistics (PRINTCOUNTER details)

Thanks to @thinkyhead for contributions.

In all these cases we want the axis to be homed. If we could have lost
some steps is secondary.

Reenables homing seperate axis with DISABLE_X / DISABLE_Y true.

Also add mbl.z_offset to the EEPROM, bumping the version to V23.

Following up on #3231

documentation/LCDLanguageFont.md moved to http://www.marlinfirmware.org/ at commit 12d0983757,
but http://www.marlinfirmware.org/ isn't working.

Redo of #2939 rebased against RCBugFix

Keep "astyled" reformatting

Apply `ENABLED` / `DISABLED` macros to language-related files.

and translate them to German.

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

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