Add bq Witbox 3D printer

Make EEPROM storage consistent

Fixing wrong pin to heater extruder 2 <-> 3

- Also adds a language string for the error.
- Also adds SERIAL_EOL as an alias for SERIAL_ECHOLN(“”)

Should be reading 4 x 4 PID values instead of 4 x 3

Formatting cleanup of quiet sources

Rename lastnr to autostart_index and...

language files smaller. Also removed remaining unused strings.

Split up pins.h to make pins more manageable
