[Xastir] I-gate setup

[Lynn W. Deffenbaugh (Mr)]

I believe you're describing the following feature described at 
http://www.aprs-is.net/IGateDetails.aspx

> Gate all packets to RF based on criteria set by the sysop (such as

In APRSISCE/32, I'm calling that "filtered" -IS to RF gating.  This is 
not required but is allowed by the specification.  What I've read that 
xastir implements for -IS to RF gating is described as:

> Gate message packets and associated posits to RF if all of the

Where "message packets" are the APRS-specified messages defined by 
datatype : (colon) and described in Chapter 14 of aprs101.pdf.
