 Using allowed_themes filter allows only to set themes which are displayed
 for choosing.

 Unfortunately if we add single exclusive theme for just one blog - user
 can't use it.

 This is due to check in "is_allowed" method of WP_Theme class. It doesn't
 involve allowed_themes filter and fails with "Cheating, huh?" warning.


 Steps to reproduce:

 1. Use filter to add exclusive blog:
 {{{
 add_filter('allowed_themes', function($tpls) {
    if(logic) {
       $tpls['exclusive_theme'] = true;
    }
    return $tpls;
 }
 }}}

 2. Try to enable it through themes menu.

 Expected result: theme is changed
 What happens instead: "Cheating, huh?" warning is displayd.



 Possible fix included.
