	* app/gimpdnd.[ch]: Made file/url DND work like the other DND types.
	The drop callback gets passed a GList of filenames.
	Provide a default callback which calls file_open_with_display()
	for each filename.

	* app/docindex.c: changed accordingly.

	* app/gui/toolbox.c: same file DND changes and made dropping
	drawables work again with the new DND system.

	* app/widgets/gimpdrawablelistview.c: properly disconnect from the
	image in "destroy".

	* app/widgets/gimplayerlistitem.c: gtk_signal_connect_while_alive()
	to the layer's "mask_changed" signal.
