Status codes wrong

[ThomasBerends]

Example:
http://demo.opencart.com/index.php?route=product/manufacturer/info&manufacturer_id=randommistake

This page is not found, but gives a status 200. If somebody accidentally links to this page, search engines will find it and index it.

This also works for categories:
http://demo.opencart.com/index.php?route=product/category&path=anothermistake

This has been resolved on the 1.5.6.1 branch now, see the recent commits.

Just add

$this->response->addHeader($this->request->server['SERVER_PROTOCOL'] . '/1.1 404 Not Found');

before the not_found.tpl is loaded.
