Kevin O'Connor cf6c5e6f18 gcode: A set temperature request should use the heater name, not the gcode id
When setting a temperature, lookup the heater via
self.heaters.lookup_heater() and do not use the gcode ids.  This fixes
temperature setting when multiple extruders share the same heater.

Andy Silverman b22a81cd34 heater: Added config for heater PWM cycle time.
Added the pwm_cycle_time option for heater config sections.  Defaults
to previous value of 0.100 seconds, but may be reduced to shorter times
at the expense of MCU workload and possible MOSFET heating, depending on
controller design.  Some printers that need bed PID to be enabled,
notably the Felixprinters series, are known to benefit from shorter
cycle times, as the default 10hz rate results in excessive voltage
supply droop.

While this option can be used on extruder heaters as well, there
is not expected to be any particular benefit from doing so unless
the extruder heater presents a particularly large load.
