Keep up to date with robopaint method-draw branch
Make that cncserver is cleared and not paused on startup
On mode close, clear out buffer and clean up/park regardless of state
Fix method-draw save cancel (don't save with no path!)
Also convert lines and polylines on transfer
Attempt to make method-draw file saves cleaner!
