Make it possible to set the coordinates via map for all selected dives.

This patch makes it possible to set the coordinates on the map for
all selected dives. Note however that after a coordinate is set,
user cannot edit it unless he multi-edit it with a dive that doesn't
have coordinate's set. this is just because it's missing a 'edit coords'
button.
