Simple script to setup a safe shutdown on Lakka+RetroFlag

Works on NESPi and SNESPi cases.

1. Connect rPi to internet
2. Boot up Lakka
3. Config -> Services -> SSH Enable -> On

scp <repo> root@<rpi>:/tmp/safe-shutdown
ssh root@<rpi> cd /tmp/safe-shutdown && bash install.sh

This is pretty much a cleaned up version of:

Inspired by:

Uses the RPi.GPIO module (https://sourceforge.net/projects/raspberry-gpio-python/). The one embedded seems to be 0.5.11, compiled for Python 2.7.
