[Xastir] Pi scripts

[Dexter N Muir]

Lee, FYI

    I've just updated my Kubuntu install at the rest home (I spend a 
week there each couple of months - respite for my wife). The update 
invalidated the previous install, so it was a necessity.

    Your Pi scripts could use an update: I copied the if - fi block for 
xenial 16.04 and renamed as bionic 18.04, and all worked flawlessly. I'm 
now happily running 2.1.1
