Support DOI query for conference paper

Currently, X7 (v7.7) is able to autofill the citation data for journal article using DOI (via “Find Reference Update”). However, for conference paper, it doesn’t fill-up the conference name, date, and location (if I select “Journal Article” ref type). The query doesn’t work (“No updates were found at the time”) if I select “Conference Paper/Proceedings” ref type.
DOI does provide conference info (check crossref.org).
