Poll should provide node to form theme function

Some sites wants to display poll links (results, older polls, comments) on the poll voting form even if the user hasn't voted yet. This can easily be accomplished via theme_poll_view_voting but only if the $node object is available since that is where the links are set.

The attached one-line patch provides the necessary info.

If this patch is committed, the following template.php snippet for displaying the poll results in the form could be posted:

function MYTHEME_poll_view_voting($form) {
  if (is_array($form['node']['#value']->links)) {
    $form['links'] = array
      ('#type' => 'markup',
       '#value' => ('<div class="links">'.
                    theme('links', $form['node']['#value']->links).
                    '</div>'),
       );
  }
  return theme_poll_view_voting($form);
}
