Common -> Complete Implementation of Generic HTTP Interface (and REST) devices.   Refactor Command from Ventilate to Circulate.  Update Unit Tests
HAInterface -> Handle logging a bit better for non scalar types.  Add some comments to make functions a little clearer to those that read them.
Thermostat -> Update generic Thermostat class to have a "Circulate" command.
HW Thermostat -> Finish basic implementation.  Allows for control of Circulation FAN on and off.   All of the hard work is done. Just need to crank out the rest of the commands.
