The "Random Cycle" does not support more than one device

[Teraskull]

The Random Cycle timer has to be completely reimplemented, because it was relying on the all_devices config.

Now that every device can have different effect_random_cycle settings , for example: device_0 :

"interval": 10

device_1 :

"interval": 15

The timer can't track multiple devices and different intervals.
