mustard: Aggiunti controlli per gestione in massa delle notifiche.

* web/mustard/js/notifs.js.php: Aggiunte funzioni per cancellare e
  marcare come lette che operano su liste di notifiche.
* web/mustard/notifs.php: Quando riceve una POST con un body JSON
  esegue un'azione su liste di notifiche.
* web/mustard/notifsh.php: Le notifiche non vengono più cancellate dal
  DB ma vengono marcate "deleted".
* web/mustard/theme.css: Aggiunta classe "deleted".
