forms: Try to disable autocomplete on forms with password fields

By default browsers (at least chrome is very agressive) try to detect forms
with password inputs and try to insert saved passwords (for example from the
login page). The default attribute to disable this (autocomplete=off) is
ignored sometimes. Therefore we add two hidden input fields, that disable
the auto filling at least in chrome.
