Fix the XML gps parsing and saving when using non-US locales

The GPS parsing and saving was using sscanf and sprintf respecively, and
since it is using floating point values (boo!) that affects both of
them.  In a C/US locale, we use a period for decimal values, while most
European locales use a comma.

We really should probably just fix things to use integer values (degrees
and nanodegrees?) but this is the simplest fix/workaround for the issue.

Probably nobody ever really noticed until I tested the Swedish locale
for grins, since we don't have a good way to actually set the GPS
coordinates yet.  I've got a few dives with GPS information that I
entered manually.
