New general release

General release for all supported boards.

Changes:

• Fix for safety door, feed hold and cycle start bits

Hints:

• Always connect endstops to X-MIN, Y-MIN and Z-MIN of the board, independant of endstop position
• Define homing direction with $23 (see https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#23---homing-dir-invert-mask)
• Laser PWM on Pin 2.5 (use minus pin of MOSFET connector)
• Default settings are for K40 chinese laser engraver
• $33 setting for PWM frequency (default 5000Hz)
• Set $5=0 if you have normaly open (NO) endstopps

Coolant Flood and Mist M7/M8/M9 Pin mappings (depending on available MOSFETs of board):

• Smoothie: Flood P2.4, Mist P2.6
• C3d Remix: Flood P2.6, Mist P2.7
• C3d Mini: Flood: P2.6, Mist: P2.7
• MKS SBase: Flood: P2.6, Mist: P2.7
• Azteeg X5: Flood: P2.4, Mist P2.7
