Added an argument to get the model.

2002-02-12  Christopher James Lahey  <clahey@ximian.com>

	* gui/widgets/e-addressbook-reflow-adapter.c
	(addressbook_get_arg): Added an argument to get the model.

	* gui/widgets/e-addressbook-view.c (writable_status): Don't bother
	connecting to the writable_status callback on the book, simply
	rely on the writable_status callback on the addressbook model.

	* gui/widgets/e-minicard-view.c, gui/widgets/e-minicard-view.h
	(set_empty_message): Handle the case of a read only view here.
