Backport from HEAD. Fix for Vote widget display in issue #159072. The widget did always show in the teaser. Make use of HTTP_X_FORWARDED_FOR for anonymus voting. Using drupal_add_feed() to create feed links. Make sure the top pages onle cound votes that are for nodes and not for comments with the same id. Changed path from votes to votesupdown. Coding style fixes, thanks coder module.
