Resolved bug with adjustECtemp timer
Fixed magic bug that sometimes showed blue watering message and
sometimes didn't. It still has a magic cause but it's fixed with a
properly-placed gui refresh.
Now system will begin watering again if stopped for the night and
appropriate setting changed
Now screen is refreshed before led color change. This makes it appear as
though both things happen at once
Serial debug messages added when stopping/starting watering because of
nightTime or settings change
