Merge branch 'dev/led'

* dev/led:
  millis() rollover fixes; reintroduce anti-poisoning options
  Fading LEDs via PWM; v8c mod (LED = pin 9) to fix tone() conflict with PWM on pin 11; reverse relay control polarity (since HIGH = open circuit = device off); switchPower via Alt rather than Adj; retire SelFn/AdjFn variables; rename night-off and day-off to night and away modes
  Retire mainSelFn, mainAdjFn, altSelFn. Their functions are baked-in now.
  Snooze cancel signal should use beeper when relay is switched; remove unused config lines
  v8a/b configs: rename to reflect PWM change; include version with sel/alt flipped
  v8 mod test: tell which button was released
  v8a and v8b isolated tests; mods to code for v8a and v8b (untested)
  Test sketch for modified v8.0 boards
  ibid
  three v8 configs, initInputs bugfix, remove unimplemented options
  External config files, option number changes, v8 config file set up for input mod testing
  Temp option + persistent display + write display to console, for testing ; further (untested) work on LED circuit switching
  (Unfinished, see stopping place) Support for LED control; use eeprom update instead of write
