Added support for PH (up to two sensors) (support for external amplifiers PH-45020)
Added timers for PH sensors (two timers are used, one for each sensor) to control load channels.
Added the ability to calibrate. Calibration manual + new client will be issued in the coming days.
With the advent of a new type of timer, their priority has changed:

PH - TEMP - MIN - SEC - DAY (i.e. PH will be with the highest priority then temperature then the rest ...)
