Add a set_shutdown_speed() method so that the heater_fan code does not
need to peek into the fan object's internal members.

If the fan's max power is limited by the config, then scale speed
requests between 0 and max_power. This makes more sense for typical
g-code fan speeds.

Add a PrinterHeaters class that can stores references to available
temperature sensors and stores references to instantiated heaters.
Add a extras/heater_bed.py file and delay instantiation of the
heater_bed object. This allows the heater.py module to be imported
earlier during the setup phase, and allows the PrinterHeaters class to
be available for registering sensors and heaters.

Use both load_config() and load_config_prefix() functions when
dynamically loading a module from the extras directory - if the config
section name has parameters in it then use load_config_prefix().

The print cooling fan and printer heater_fan are independent modules
that can reside in the extras directory.
