Does background saves of node being edited.

Code

  // TODO: Do something clever for not just node forms.
  global $user;
  $path = $_POST['autosave_form_path'];
  $path_args = explode("/", $path);

  // check if node has just been saved - if it has then it's because AS ajax fired off as user was submitting
  // if it had just been submitted - no need to AS now
  //    - easy to figure out if we are submitting an edit to existing node
  //    - little harder if we have just added a node
  if ($path_args[0] == 'node') {
