Citoid: Add BibTeX as export format
completed by: Geoffrey Mon
See https://phabricator.wikimedia.org/T1083 for the corresponding bug report. In the file server.js, 'mediawiki', 'zotero', and 'mwDeprecated' are allowed export formats for both the 'url' and 'api' endpoints. However, scientists love BibTeX! Zotero's translation-server can translate between the 'zotero' format and a number of other formats, including bibtex. In translation-server, check out the file translation-server/build/translation-server/server-translation.js which documents the "export" endpoint.
