The global object "displayed_dive_site" is used to store the old dive site data for the edit-dive-site widget. The fields of the widget were initialized from this object in the show event. Therefore the object was updated in numerous parts of the code to make sure that it was up-to-date. Instead, move the initialization of the object to the function that also initiatlizes the fields. Call this function explicitly before showing the widget. This makes the data-fow distinctly easier to understand. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
