Made it so that all of these functions queue their ops before calling
2001-06-11 Christopher James Lahey <clahey@ximian.com> * backend/ebook/e-book.c (e_book_load_uri, e_book_get_supported_fields, e_book_authenticate_user, e_book_remove_card_by_id, e_book_add_vcard, e_book_commit_vcard, e_book_get_cursor, e_book_get_book_view, e_book_get_changes): Made it so that all of these functions queue their ops before calling their CORBA functions. This way, if the response is sent back before the CORBA function returns there's no problem. Added e_book_unqueue_op so that the op could be unqueued if the CORBA call fails. svn path=/trunk/; revision=10180
