Ramp up layer cooling fan over X layers #848

Browse source 
Fan speed will be ramped up linearly from zero at layer disable_fan_first_layers
to maximum at layer full_fan_speed_layer. full_fan_speed_layer will be
ignored if lower than disable_fan_first_layers, in which case
the fan will be running at maximum allowed speed at layer
disable_fan_first_layers + 1.;

WIP: The cooling PresetHints are likely not finalized yet.
