Added Grbl state in status report. Removed switch support.
- Added Grbl state (Idle, Running, Queued, Hold, etc) to the real-time status reporting feature as feedback to the user of what Grbl is doing. Updated the help message to reflect this change. - Removed switches (dry run, block delete, single block mode). To keep Grbl simple and not muddled up from things that can easily be taken care of by an external interface, these were removed. - Check g-code mode was retained, but the command was moved to '$C' from '$S0'.pull/1/head
