[Xastir] Search RAC Database Button

[Frank Tomesch]

While using the latest development snapshot of xastir 1.9.5 I came accross 
the following problem.  VO2RS appeared on the map.  When I right click on 
him to open his station information the "Search RAC Database" button is 
missing.  The data is in the RAC database that I down loaded.  I assume 
the button is missing since his call prefix isn't VA or VE.  The same 
problem might also occur for VX and VY prefixes.
