Back-ported Fabrikator Mini config changes. Not tested before commit.

Add PROBE_MANUALLY support to G33

UTF-8 mapper for Czech

Add configurable action command to send when printer is killed

DISABLE_[XYZ] compatibility check

DISABLE_[XYZ] is incompatible with HOME_AFTER_DEACTIVATE and Z_SAFE_HOMING

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

Fix for issues #6997 and #7152

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.
