casting issue in biblio_save_node()

biblio_save_node() creates a new node when it imports a biblio item and later saves it with node_save(). It fails however to set some of the node object with the proper type (promote, moderate, sticky, status) which causes some nasty behavior upon saving. For example when importing a biblio node with some taxonomy terms, you might get SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'sticky' at row 1: INSERT INTO {taxonomy_index} (nid, tid, sticky, created) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3); because sticky is not set.
