Added the function e_book_view_listener_stop to tell the book view

2001-04-14  Christopher James Lahey  <clahey@ximian.com>

	* backend/ebook/e-book-view-listener.c,
	backend/ebook/e-book-view-listener.h: Added the function
	e_book_view_listener_stop to tell the book view listener to stop
	sending signals.

	* backend/ebook/e-book-view.c (e_book_view_destroy): Tell the
	EBookViewListener to stop when we're destroyed.

	* backend/pas/pas-backend-file.c (view_destroy,
	pas_backend_file_process_get_book_view,
	pas_backend_file_process_get_changes): Cleaned these up a bit
	using bonobo_object_ref and bonobo_object_unref.
	(pas_backend_file_process_get_book_view,
	pas_backend_file_process_get_changes): bonobo_object_release_unref
	the EBookListener here.

	* backend/pas/pas-backend-ldap.c
	(pas_backend_ldap_process_get_book_view): Cleaned this up a bit
	using bonobo_object_ref.  Make sure to unref the listener when
	we're done with it.  Put the new book_view in the list before
	telling the book_listener that it's ready.

	* backend/pas/pas-book-view.c (pas_book_view_construct): Cleaned
	this up a bit using bonobo_object_dup_ref.
	(pas_book_view_destroy): Cleaned this up a bit using
	bonobo_object_release_unref.

	* backend/pas/pas-book.c (pas_book_queue_get_book_view,
	pas_book_queue_get_changes): bonobo_object_dup_ref here instead of
	just duplicating.
