Proof of concept for reverse geo location

Browse source 
When reading a pre-v3 XML file, we now do reverse geo lookups on the GPS
coordinates and add the country to the dive site notes. Eventually this
wants to be a tag (once we implement tags for dive sites).

This is going to add quite a bit of delay when people open a V2 XML file -
depending on how many distinct GPS fixes they have. In my case with 127
GPS fixes it took about 20 seconds to open the file...
