[arm-allstar] SkywarnPlus install notes

[Steve Piotrowski]

sorry I should have replied to this group as well, I had an answer from
mason on the github Q&A. yes, he actually removed the --inject option on
the new version so it obviously wasn't working. the line by line stare and
compare is hard. i didn't know yaml was that picky.....

thanks all for the help and great documentation on skywarn plus, it was a
pretty painless install. now i'm just waiting for a blizzard or something
to actually try it!
