Suggestion: Do not load “admin-toolbar-menu.css” for not logged-in users

Good day,

I found that “admin-toolbar-menu.css” fole is loaded every time, even though for normal visitors it is not needed (i.e. this is actually bad SEO/PageSpeed practice).

It is done unconditionally in class-aioseop-core.php in the front_enqueue_styles() method.

The CSS rules from that file are used in the admin_bar_menu() method, which is used only when user is logged-in (this is checked in add_hooks()) and some other conditions.

So I would suggest that this check could be added as well in class-aioseop-core.php in the front_enqueue_styles(), so something like the following two lines would be great:

if ( !is_user_logged_in() )
    return;
