I added the fan pins in here and left them at -1 in configuration_adv.h
and it works fine. Pinned for a 4 extruder from 1-4 and HE5 being the
controller fan, HE6 being the Extruder Auto Fan/Water pump in the Kraken
case, and HE7 being for part cooling fan. Added in descriptions for the
MIN MAX pin swap and for servo motor additions.
