Add support for up to 15 profiles

I noticed the 3 profile LEDs also have an orange LED, and using the binary system with 4 bits, I could fit 16 profiles in. However that would require one of the profiles being 0 and none of the LEDs would be lit which I didn't like, so I just made it 15 profiles. I can't imagine anyone using that many profiles, but meh, why not :).
