Reset live adjust on XYZ calibration. Disable timeouts in the XYZ/Z calibration. Don't modify feed rate multiplier during the XYZ/Z calibration. Support multi screen messages in the XYZ/Z calibration - "move the Z carriages up" step. Support up to three lines in the XYZ/Z calibration messages. Added a new message "Measuring reference height of calibration point xx of 9". Changed the "move the Z carriages up" message to suggest rotating the knob. Changed the "live adjust not set" message to reference the manual chapter and section. Remove debugging serial line output on Z calibration. Removed the non-working pressure advance feature. Improved accuracy of diagonal moves by oversampling the path discretization. Accelerated the planner by rewriting time critical routines from floating point to fixed point arithmetics.
