- 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.
