Added Alexander Heinlein's alix_gpio.cpp from http://choerbaert.org/wiki/voyage_on_alix
Added comments and changed PRESS_ACTION to /etc/alix_gpio_action
Added /etc/alix_gpio_action (poweroff)
Removed LED manipulation, we do that with /etc/led_control ourselves
Would help to actually execute the configured action!
Adding binary /usr/local/sbin/alix_gpio
Adding startup script for /usr/local/sbin/alix_gpio
