title: Ignorecase for In-Criterion
body: <p>i'd like to select items case insensitive with an In-Criterion with Hibernate Criteria API.
  E.g.</p>
  
  <pre><code>Criteria crit = session.createCriteria(Item.class);
  crit.add(Restrictions.in("prop", valueList).ignoreCase());
  </code></pre>
  
  <p>Unfortunately the Criterion class doesn't has an ignoreCase method.
  HQL is not an alternative.</p>
