In my experience the GUIs remember some fields *incorrectly*, as when
they try to auto-fill a saved password into what is actually an OTP
field with the same name.

Fair point. However, I think there are cases where the other UIs could
benefit. GlobalProtect OTP puts its one-time-tokens into a field that
NM-plugin couldn't distinguish from a fixed password field. I thought
it'd be better to provide general-purpose hints to the GUI, rather
than trying to special-case this into each of them.

I did that at first, but then I had to special-case-rename the fields
to user and passwd when submitted them as an HTML form.
I rewrote it with the hints because I thought it'd be more useful to
have this general-purpose mechanism for recognizing the purpose of the
fields independently from their names.
