Create record reference field

The idea would be to let users list bib. records inside nodes in CCK fields (instead of using the millennium_filter.module) as a sort of nodereference... but the items would be embedded on the fly (or from cache) from the remote OPAC.

Users could either give just a bib/item record number, or a full URL to a record.

Bonus points: It'd be nice for rendered references to be expanded in-place. (which also applies for other portions of the module)

I *think* SOPAC 2.0 allows for such a CCK field... or see some of the code4lib guys' code repositories.
