Made a NULL callback just mean to not call back.

2000-05-07  Christopher James Lahey  <clahey@helixcode.com>

	* backend/ebook/e-book.c: Made a NULL callback just mean to not
	call back.

	* backend/ebook/e-card-simple.c, backend/ebook/e-card-simple.h:
	Reordered fields.  Added a get_const function to get a constant
	string that persists until the simple is destroyed.

	* gui/component/Makefile.am: Added e-addressbook-model.c and
	e-addressbook-model.h and all of the libraries and includes that
	they are dependent on.

	* gui/component/addressbook-factory.c: Initialize e cursors.

	* gui/component/addressbook.c: Added inactive code to display an
	ETable view of the addressbook.

	* gui/component/e-addressbook-model.c,
	gui/component/e-addressbook-model.h: New files to implement an
	ETable model with a EBook back end.
