The coordinates of a "dragged flag" were passed out-of-bound via the global "displayed_dive_site" object and then a signal was sent to notify of the changed coordinates. Instead, pass the coordinates directly via the signal. This makes the data- and control-flow more clear. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
