warn about fields that were aggressively anonymized

[irrer]

This would be a nice summary to highlight to the user what is being done, and possibly show information that should not have been anonymized.

The aggressive anonymization feature has a potential problem:

Patient's last name is 'Big' and will get anonymized to 'none'

Machine manufacturer model name is 'Big Bore'

Machine name gets aggressively anonymized to 'none Bore'

Someone familiar with the model of machine could reason that the patient's name is 'Big'
