[Xastir] limiting inbound internet traffic to RF based on call sign

[Jason KG4WSV]

found in the the help file:

"If you want to have your IGate forward NWS weather alerts to RF, you must
create a ~/.xastir/data/nws-stations.txt file listing each call or NWS station
(like "PHISVR") that you would like to transmit via RF.  This feature also
works for gating specific callsigns to RF."
