heater: Introduce smooth_time config option; remove pid_deriv_time

Browse source 
Add generic temperature smoothing to the Heater class.  This is useful
to avoid min_extrude_temp and verify_heater errors due to measurement
noise.

Rename the pid_deriv_time config option to smooth_time so that the
smoothing amount need only be specified once.
