New variable added to form to specify whether it should autofill or
not. This updates the modal forms autocomplete attribute. Hidden
fields are required because Chromium v34+ based browsers ignore the
autocomplete=off form attribute, so the hidden fields catch autofill
data. Any form without self.no_autocomplete = True will just act
like before.
