Subject: [PATCH] Bug 20888: Allow use of boolean operator 'not' in item search

Test plan:

 - Apply the patch
 - Check that you have a 'is not' option in the third box in item search
 - Check that you can exclude items from the search results with this 'is not' option
 - Check that you can still combine parameters with 'and' and 'or'
 - Check that the exclusion works for custom fields (see Administration > Item search fields)
 - Check that the exclusion works for custom fields linked to authorised values
