Add 'switch to temperature mode when pump turns on' option

[tooluser]

Lantern should switch to temperature mode when the pump turns on.

This could be annoying, because the pump may turn on many times a day. For example, it may turn on to run as a cleaning cycle.

Instead, I will leave this to individual taste - the device is already fully controllable. In my own case, I'll include it in my 'heat up the hot tub' action.
