Missing textdomain in Tutor settings string

Hi,

Me and other translators are working on French translation (100% today ! :-)) of your plugin.
There is a string which we cannot translate because textdomain is missing in source code : /tutor/views/options/options_generator.php on line 2 :
<h1><?php _e('Tutor Settings'); ?></h1>

Can you, please, add your textdomain ?

Thanks you !
