Translatable linked datas displayed in wrong language

[aurmil]

when displaying translatable datas in back office, browser language is used instead of back office language this is due to "new Zend_Locale()" instanciation in library/Centurion/Contrib/translation/controllers/helpers/ManageLanguageParam.php without nay param, it takes brower language language should be the one used in back office

possible fix:

$controller = $this->getActionController();
if (!($requestedLocale = $controller->getRequest()->getParam('language', false))) {
    $bootstrap = $controller->getInvokeArg('bootstrap');
    $options = $bootstrap->getOptions();
    $default = null;

    if (isset($options['resources']['locale']['force']) && (1 == $options['resources']['locale']['force']))
    {
        $default = $options['resources']['locale']['default'];
    }

    $local = new Zend_Locale($default);
    $requestedLocale = $local->getLanguage();
}
