Allow more flexible GPS coordinates for CSV import

This theoretically allows one to use format like
1°36'11.711"N 124°46'00.368"E for GPS coordinates. However, in practice
this is not allowed without properly parsing this format in C/C++ side.

This patch changes the export format to UTF8 and improves the location
import by allowing either gps or location attributes to be imported.
