Additional columns for the resolved_reference table

[ehenneken]

For the support of calculating metrics data, the resolved_reference table should have the following two additional columns:

1. publication_year (publication year for the matched publication, integer)
2. refereed_status (refereed status for the matched publication, 0 or 1)

These can be populated based on the output of the reference_service (after implementation of this issue)
