Add autocomplete attribute to known password fields.

[rfeese]

Description (*)

Add "autocomplete" attribute to password fields on customer-facing forms. This is not really a security issue in my opinion, but this change is intended to help meet PCI attestation requirements. Some vulnerability scanners are known to flag this as an issue. For example: https://www.tenable.com/plugins/nessus/42057

I attempted to use the most appropriate value for the attribute (off or new-password). These changes should not have any noticeable impact on users.
