This is already dealt with for coast lines, so it shouldn't be much of
a jump to deal with country borders in a similar way.

At present we're using multiple relations where the name changes along
a route but the ref stays the same and vice versa so it's not possible
with the current pre-processing that is done to do a nice little query
to get the shield and name from the same query. I have no idea how to
fix this.

The other biggy is dealing with the country borders during
pre-processing, again no idea how to do this.
