Can we have a script for LibreELEC?

[danielristic]

LibreELEC is also a very popular OS to install on a Raspberry PI and it does not seem there is a simple way to set up safe shutdown on it with a RetroFlag case.

[MikeBergmann]

Installation on LibreELEC is straightforward:

• Install the pi-tools add-on via LibreELEC GUI to get RPi.GPIO
• Follow dtbo installation from install script:

  retroflag-picase/install.sh

  Lines 13 to 30 in fb69441

  	File=/boot/config.txt
  	wget -O "/boot/overlays/RetroFlag_pw_io.dtbo" "$SourcePath/RetroFlag_pw_io.dtbo"
  	if grep -q "RetroFlag_pw_io" "$File";
  	then
  	sed -i '/RetroFlag_pw_io/c dtoverlay=RetroFlag_pw_io.dtbo' $File
  	echo "PW IO fix."
  	else
  	echo "dtoverlay=RetroFlag_pw_io.dtbo" >> $File
  	echo "PW IO enabled."
  	fi
  	if grep -q "enable_uart" "$File";
  	then
  	sed -i '/enable_uart/c enable_uart=1' $File
  	echo "UART fix."
  	else
  	echo "enable_uart=1" >> $File
  	echo "UART enabled."
  	fi

• Copy https://github.com/RetroFlag/retroflag-picase/blob/master/SafeShutdown.py to /storage/.config/RetroFlag folder
• Patch the script with the patch below.
