Order status languages not loaded, with fix

-- HikaShop version -- : 2.3.4
-- Joomla version -- : 3.3.6

There is a DS missing on line 1358 in administrator/components/com_hikashop/classes/order.php which leads to problems loading correct translations and overrides when sending order status change messages:

Before:

$override_path = JLanguage::getLanguagePath(JPATH_ROOT).DS.'overrides'.$locale.'.override.ini';

$override_path = JLanguage::getLanguagePath(JPATH_ROOT).DS.'overrides'.DS.$locale.'.override.ini';

We here at Sydweb stumbled upon this when building a site for a client, and made this fix that works at least for us.
