Bring back dragging of elements from the clipboard to the activities - SL #4485

This is another API fix for code not yet ported to GTK+3, similar
to #3819:

- gtk.SelectionData.type  ->  Gtk.SelectionData.get_data_type()
- context.set_icon_pixbuf(...)  ->  Gtk.drag_set_icon_pixbuf(context, ...) [2]
