Set appropriate autocomplete attributes on password fields

[silverwind]

new-password prevents annoying autocompletion in some cases, thought it's not semantically correct to use that for example on all three fields on the user account page, so some annoyances remain.

I've set this as 1.14 but if it's approved before 1.13 is ready I think it would be reasonable to merge before.

All current browsers will still ignore autocomplete="off" but it will not hurt :)

All current browsers will still ignore autocomplete="off"

I'm still hoping that some password managers will eventually start to honour it 😉

There's one minor remaining issue on the user account page that my password manager autofills current password so the form will be considered dirty by jquery-are-you sure. Maybe that field can be ignored from dirty check, will have to check later.
