[Xastir] Changed Callsign

[Clay Jackson]

In case someone else makes the same stupid mistake -  

I'm setting up my Xastir instance as a Fill-In Digi and iGate.  I've been
using N7QNM as a callsign forever.

Last night, as a "final" step; I changed the callsign to PROSSR (to reflect
the location).   Right after that; I noticed that my iGates were no longer
going anywhere.

I forgot to use "callpass" to change my validation code.....

Doh!
