Version 0.9.0. Implemented DCMD via mqtt to set stage, mode, setpoint low and high. Implemeted DCMD via mqtt to set heater, cooler, fan and light state. Implemented DCMD via mqtt to set product code and name. Set the PID's in fridge mode without idle range offset, that was an old leftover setting that was obsolete.
