Language loader class should be $config['lang_code']

[eluser]Ki[/eluser]
In the core/Lang.php lines 72 and 73 should be
$config['lang_code'] instead of $config['language'] because it is $config['lang_code'] in the config.

Code:

$deft_lang = ( ! isset($config['language'])) ? 'english' : $config['language'];
            $idiom = ($deft_lang == '') ? 'english' : $deft_lang;
