issue 22+37, pretty stable, compiles on my machine

will do: move power on delay, let no cycles be wasted. make leds.py nicer. add another way to save power, hierarchy must only be active during data transmittion, after that even led 14 can be switched off when the top leds are still active i think. will adjust initial rgb channel gammas as soon as i get my hands on final hardware

enjoy =D
