Clean up logic within updateValue and checkThresholds

Work around problems with floating-point equality
Require small difference in order to publish new value
Always check thresholds, regardless of magnitude of change
This avoids problem of small change not triggering thresholds
Using "Schmitt trigger" logic to avoid threshold jitter spam
If threshold changed, threshold will always be checked next reading
This avoids problem of threshold changes not taking immediate effect
Added debugging counters for testing checkThresholds
