        * wptListview.cpp (listview_del_sel_items): Fixed index
        calculation. This fixed a lot of problems with the KM listview
        update.
        (listview_del_all): Renamed to...
        (listview_del_all_items): ..this. Changed all callers.
        * wptKeyManagerDlg.cpp (keymanager_dlg_proc): Just refresh
        list when file import contained new/updated keys.
        * wptKeyManager.cpp (km_file_import): Indicate if the
        import contained any new/update keys.
        * wptClipImportDlg.cpp (print_import_status): Just mark
        keys which actually changed.
