Blink my LIFX lights to wake me up

LIFX has great Schedules built-in to fade in my lights for a gentle wake-up. But sometimes a gradual fade-in is not enough to wake me. This recipe flashes my lights for one whole minute to make sure I've really woken. I just power the light off via the app or wall switch to stop it flashing if I don't need the whole minute of flashes.
