- Add hc jobs server log output and consolidate log reversal and log output into the jobs service.
- Add hc connect (without parameter) to try and auto connect to scanned serial ports, and stops at the first GRBL controller found.
- Modify log output to retain space between gcode commands for readability.
- Fix to avoid streaming empty lines from gcode files to avoid unexpected streamer code repetition.
- Fix to remove both line feeds and carriage returns correctly when processing gcode files.
