NOTE: Another incremental update. Likely buggy, still a ways to go before everything is installed, such as startup blocks. - Changed the '$' command to print help. '$$' now prints Grbl settings. The help now instructs the user of runtime commands, switch toggling, homing, etc. Jogging will be added to these in v0.9. - Added switches: block delete, opt stop, and single block mode. - Now can print the g-code parser state and persistent parameters (coord sys) to view what Grbl has internally. - Made the gc struct in the g-code parser global to be able to print the states. Also moved coordinate system tracking from sys to gc struct. - Changed up the welcome flag and updated version to v0.8c. - Removed spindle speed from gcode parser. Not used.
