Version 0.3.44. Moved iSpindel Plato calculation from the php script to bmsd. This uses calibration data in the mon_ispindels table. Setup of this data will be done by the bmsapp applications. Default settings are stored in MySQL. From now on you don't need to store calibration data in the iSpindel.
