Added the functionality to delete selected (multiple) dives

Moved portion of the code from delete_dive_cb() to a function called
delete_single_dive(), that directly accepts a GtkTreeIter pointer.

Added the function delete_selected_dives_cb(), which is called
when calling "Delete dives" from the combo box for the selected dives.

The above function iterates trought the selection calling
delete_selected_foreach(), which on its own calls delete_single_dive().

The "for-each" API in this case looks much prettier C code wise,
however we do potentially create an extra jump and also
do not have anything but the redirection:
delete_selected_foreach() -> delete_single_dive()

Probably slighly slower than using gtk_tree_selection_get_selected_rows(),
performance wise, but less C code.
