hook up contact_changed/contact_removed signals. (contact_changed): new

2004-02-02  Chris Toshok  <toshok@ximian.com>

	* gui/widgets/e-addressbook-view.c (eab_view_new): hook up
	contact_changed/contact_removed signals.
	(contact_changed): new function.  if the changed contact is the
	one we're displaying, re-render it.
	(contact_removed): new function.  if the removed contact is the
	one we're displaying, clear the display.
	(render_contact): set displayed_contact to the row.
	(eab_view_init): init displayed_contact to -1.
	(selection_changed): set displayed_contact to -1 when we clear the
	display.

	* gui/widgets/e-addressbook-view.h (struct _EABView): add
	"displayed_contact" so we can update the contact preview when it
	changes.
