Added Fan control to the pre-heat settings.

Browse Source 
I find that the PID routine works better when the cooling fan is switched on
at the beginning of a warm up routine.  Otherwise when you enable the fan
just before a print, you have a delay as the PIDre-adjusts.

This should also be safer as most cooling fans are directed at the hot -ends
thermal barrier!
