---------------------+------------------------------------------------------
 Currently, adding categories via AJAX output a generic error message when
 something goes wrong in wp_insert_category() since that function does not
 return WP_Error for back-compat reasons.  Let's add an option to
 wp_insert_category() that tells it to return WP_Error instead of 0.
