    opensubtitles: Fix delete-event callback signature
    
    gtk_widget_hide_on_delete (widget) is not a callback function. Using
    it as a callback function to "widget::delete-event" signal ( which
    takes 3 args for callback ) in C code works, though this is not
    correct. Python checks for argument count of callbacks, and so this
    hack doesn't work for python code. So, we move it UI file to trigger
    native callback.
