[Improvement] Different light patern for different tasks

[cucholix]

For example one blink on the home button for emuiibo emulation ON, long blink for emulation off, 2 blinks for swapping amiibo.

Of course an example you could find a better pattern

[deurk]

Agreed. Would be very convenient. I'd personally go for:

• 2 blinks for emulation ON
• long blink for emulation OFF
• 3 blinks for emulation ONCE
• 1 blink for previous/next amiibo

Done for 0.3 rewrite, different patterns are used for turning on, off, and when cannot move to next amiibo.
