Tidied up delta auto-calibration code. We now use least squares for 3, 4, 6 or 7-factor calibration. When doing delta calibration, if a probe offset was used to adjust the head position when probing, use the actual head coordinates instead the probed coordinates. Bug fix: newline was missing at end of SD card file list sent to USB when in Marlin emulation mode. Bug fix: Heater average PWM report (M573) sometimes gave inaccurate values when the S parameter was used.
