Provide additional information for appoximate QID matches

[diegodlh]

When getting an item's (either citing or cited) QID, if no exact match is available, a list of approximate matches may be offered. However, this list includes only the approximate match title and QID. Including authors and publication year may help the user decide if the match suggested is the one they are referring to.

Can the reconciliation API send this data? Or do we have to make a separate Wikidata API call?

This issue is related to #101

It says in the openrefine-wikibase documentation that "the types and any other property used for reconciliation is also fetched on the candidate items (again with wbgetentities)". So that if author name and publication date are included in the query (#103), they should be included in the response as well.
