(NOTE: This push is likely buggy so proceed with caution. Just uploading to let people know where we're going.) - New report.c module. Moved all feedback functions into this module to centralize these processes. Includes realtime status reports, status messages, feedback messages. - Official support 6 work coordinate systems (G54-G59), which are persistently held in EEPROM memory. - New g-code support: G28.1, G30.1 stores current machine position as a home position into EEPROM. G10 L20 Px stores current machine position into work coordinates without needing to explicitly send XYZ words. - Homing performed with '$H' command. G28/G30 no longer start the homing cycle. This is how it's supposed to be. - New settings: Stepper enable invert and n_arc correction installed. - Updated and changed up some limits and homing functionality. Pull-off travel will now move after the homing cycle regardless of hard limits enabled. Fixed direction of pull-off travel (went wrong way). - Started on designing an internal Grbl command protocol based on the '$' settings letter. Commands with non numeric characters after '$' will perform switch commands, homing cycle, jogging, printing paramters, etc. Much more to do here. - Updated README to reflect all of the new features.
