Added support for Duet 0.8.5 with auto detection between 0.6 and 0.85 board types Added P parameter to M115 command to set board type Changed M115 output to report the board type that was configured or auto-detected Improved ISR and step pulse generation efficiency to allow higher movement speeds, especially wheh using 0.9deg/step motors Added XYZE parameters to M569 command to allow driver remapping Added R parameter to M569 command to allow enable signal to be reversed when using external drivers (thanks dnewman) Removed M558 R parameter because boare type 0.7 can now be set via M115 instead Moved Fan0 RPM sense pin to PA14 to avoid conflict with Duet 0.8.5 FAN1 pin M408 poll command can now be handled concurrently with other commands
