[Xastir] New capability: 2008 Tiger Shapefile street maps

[William McKeehan]

This is exactly the information that I was looking for, thanks!

One thing that I notice is that when I am at a zoom level that is out pretty
far, like 768 or so, it takes a long time for Xastir to run through all of the
maps. Much of the map data is repressed by the dbfawk files, but Xastir still
has to process it.

Is there a way to break out each component from the files, then select max
zoom on them in Xastir to allow Xastir to skip them at the file level?

Thanks again for all of the hard work to get these looking as well as they do!
