Metaboxes toggle not working

[Aboelabbas Shahwan]

While I was exploring the framework I noticed that the toggling doesn't work in the theme-settings page.

The problem is that the function momtaz_settings_page_load_scripts() always returns and doesn't echo the scripts, because the 'parent_base' of the screen object is null.
