Don't use node_save() use drupal_execute()

This patch removes the node_save() for drupal_execute(). the advantage with this new approach is things like pathauto, comment settings an other things work that have a default value in the node form. Makes things an aweful lot more drupally, still though not the best. If a form element doesnt have a good default value, then it won't work. Things like simple taxonomies that are required probably won't work.
