[easytag] Handle delete-event response from dialogues

[David King <davidk src gnome org>]

commit b55faaec5c20b0baba86e2b1dcf986bf70764088

    Handle delete-event response from dialogues
    
    GTK_RESPONSE_NONE only occurs if the dialogue is shown programatically,
    which is not the case in EasyTAG, so handle GTK_RESPONSE_DELETE_EVENT
    instead.
