[Xastir] Xastir 2.0.6 easy update here

[Kurt]

I build from scratch on a slack distro so I learned to "build" all the support in I need before
./configure, make and make install of Xastir.  I just look at the information screen after ./configure and go from there.
I just built 2.0.6 and by golly it fired up just fine after the install.  Easy update here

Only thing I wished could be done is the ability to monitor another NMEA stream through another port
similar to the base station's position.  I have a remote sensing device that uses FSK modulation that sends
the NMEA strings via the ISM band to a receiver that plugs into a USB port at 9600bps.  It behaves exactly like
a USB GPS receiver. Xastir reads it perfectly except of course it interprets it as the "station" GPS as I have to configure the port to be read as such.  I can work around that a bit by putting an "object" at the base station position.

It would be nice if a second NMEA stream could be labelled and followed independently of the station GPS NMEA stream.
