Change Y1 handling in RIS

It comes from old RIS specification and used to be the "primary date" (I think). Some websites still use it as such (e.g. Wiley), while others use it as "online publication date" (e.g. Taylor and Francis). Since Y1 is not in the current spec, we'll treat it as if it's being used according to the old spec. Other uses will have to adjust on a per-case basis.
