altos/telelco-v2.0: A bit fancier with the drag-mode LED show

Continutity leds now show whether the pad is included in the drag race
*and* the continutity using four different patterns:

Drag select & igniter present:		long on, short off
Drag select & igniter missing:		short on, long off
Not select & igniter present:		solid on
Not select & igniter missing:		solid off
