Important Update:

- SelectableCore:
  - Split handling of Handle from Input() to InputHandle() method
  - Allow multiple handles to be connected to single Channel
  - Update logs to report Handle, not Channel name
- TimingCore:
  - Convert all functions to inline functions in header (remove .cpp file)
  - Add new function TimeLeft()
- WatchdogCore:
  - Bug fix: No watchdog channel, use InputHandle() method not Input()
  - Bug fix: ping ignored, use To:"watchdog" in ping command
