Deletion of Giorgio Nadali

Comment: I'm satisfied that a credible statement on the significance of the subject could reasonably be made with his writings, if only just. However, I'm not sure about the reliability of the one review present, and I wasn't able to find any more (though I'm open to someone better at looking in Italian than me), thus  wouldn't be satisfied. The non-review sources couldn't pass GNG due to independent/reliable failures
