Work on a dive localisation tool using GPS coordinates

Browse source 
For each dive recorded, place their GPS coordinates onto a map using the
OSM-GPS-MAP library.

This map is accessible via the "log" menu or the shortcut ctrl+M (M as map).

We check for the GPS coordinates "0, 0" which are the default when we do not
have real GPS coordinates set.

[Dirk Hohndel: fixed int/float math confusion, fixed some whitespace and
               coding style issues, cleaned up some comments, added a
	       missing cast to prevent a compiler warning]
