Moves deletion logic of divepoints to the Model.

Deletes the logic of divepoints to the model, this
makes automatic updates on the table on deletions.
( remember, to select dive points, ctrl+click on it.
) if you want to delete it, press 'delete', it will
be removed from the graphics part and also from the
table.

Next: delete point by clicking on the table trash-
icon.
