Display chroot names and details

Add option '-a' to operate on all chroots and '-l' to list croutonversion details.
This makes perfect sense and is much simpler - why didn't I think of that ;)
I knew you were after eliminating the redundancy but I think I'd played with it so much that I glossed over the obvious (to you).

I'll test it on my Cr-48 with one chroot and my Acer C7 with four chroots, unfortunately, I haven't used encryption on either machine so we'll need some help in that area.

Also, apologies not necessary at all, I much appreciate the guidance and sage advice.
