- Added machine position reporting to status queries. This will be further developed with part positioning/offsets and maintaining location upon reset. - System variables refactored into a global struct for better readability. - Removed old obsolete Ruby streaming scripts. These were no longer compatible. Updated Python streaming scripts. - Fixed printFloat() and other printing functions. - Decreased planner buffer back to 18 blocks and increased TX serial buffer to 64 bytes. Need the memory space for future developments. - Begun adding run-time modes to grbl, where block delete toggle, mm/in reporting modes, jog modes, etc can be set during runtime. Will be fleshed out and placed into EEPROM when everything is added.
