Pulse Emitter - 3 modes:
On signal (1st) - When the Emitter receives power, it will generate ONE pulse 1 tick long.
On update (2nd) - When the signal behind the Emitter changes state (from on to off or back again), a pulse 1 tick long is emitted.
While active (3rd) - While the Emitter is receiving power, it will emit pulses 1 tick long and 1 tick apart.
Current Toggler - When the Current Toggler receives power (even a pulse), it will toggle the outputting signal. In other words, a Toggle Flip-Flop that works with long signals.
