Try to spot stuck valves and jiggle them until they unstick

Add another couple of temperature alarm points, jog/hi and jog/lo.

If the temperature is not between jog/hi and jog/lo, assume the valve is
stuck and should be cycled to unstick it.  Invert its driven state for
jog/flip centiseconds, then wait jog/wait centiseconds before trying
again.
Add alarm and jog register settings to configured modes

NB untested - I don't have a unit with buttons to test the UI here!
Add two more preset mode settings register sets
