Added configuration settings for MQTT in config.php. Finished screen box sizes for the fermenters monitor. Select beername and code from the current brew products and send it to the fermenter. Added switch commands to the fermenter. Delay data get from the fermenter after sending any command so there is time to process the commands. Turn switches off when the mode changes. Removed 0.2 degrees setpoint diffs for low and high, the fermenter must deal with it. Prevent turning the heater and cooler together on.
