Sonny Jeon 420c7c2584 Added coolant control (M7*, M8, M9). Mist control can be enabled via config.h.
- Added coolant control! Flood control (M8) functions on analog pin 0.
Mist control (M7) is compile-time optional and is on analog pin 1. (Use
only if you have multiple coolants on your system). Based on work by
@openpnp.

- Fixed some variable assignments in spindle control.
