added option to run new backup and restore script  for LilDebi and Debian Kit users. I've made every effort to avoid backing up any of the files or folders that Android spicificly owns so as to never over write those when doing a restore.
This is not a "bair mettle" backup and restore script (because most users of the above apps could just copy the debian.img/iso file) instead this script aims to make a backup of only relovent directories and installed packages so that when you have a fresh installed Linux working again the changes you made can quickly be recovered.
