Fixes #7250

Addressing #7227

DISABLE_[XYZ] is incompatible with HOME_AFTER_DEACTIVATE and Z_SAFE_HOMING

Sends pre-defined string as action command when printer is kill.

Probing with the effector in the printing area, but an eccentric probe (e.g. allen key) outside it but still touching the bed gives meaninfull information for calibration. Since calibration is most accurate when probing as close to the towers as possible the testing was way to restrictive hence this fix.

-Update Arduino IDE extension descriptions
-Set default motor currents if not defined in Configuration_adv.h
-Support for MINIPANEL LCD
-Support for choosing internal or panel SD

Based on Infitary's own firmware settings.

===============================================

also an issue with ubl_motion.cpp

Also corrected compile issue when DEBUG_GCODE_PARSER and
AUTO_BED_LEVELING_UBL are both enabled.

Allows the user to send text to the serial console in order to
communicate with a host - sending debuging information or action
commands, for example.  Text must begin with '//' and this is added if
it is not already present at the beginning of the string.
