New text domain

Hi,
Thank you for your plugin. It is great! But I encounted an issue with localization since last version. You’ve changed text domain in all localization functions all over the pugin files but forgot to change it in class-wad.php:
$this->plugin_name = 'wad';
So my translation file was ignored until I changed from ‘wad’ to ‘woo-advanced-discounts’.
Be so kind to change it in your next versions of the plugin.
Thank you.
