R-Pi On-board LED CLI

[rjcorwin]

It turns out we can control one of the LEDs on the R-Pi board. Wouldn't it be cool to have a CLI with an API like the blink1 cli?

# turn off the default behavior of the LED
echo none >/sys/class/leds/led0/trigger
# Turn it on
echo 1 >/sys/class/leds/led0/brightness
# Turn it off
echo 0 >/sys/class/leds/led0/brightness
