Add Complete Records for Crossref (crossrefComplete) 1.0.0.5 — OJS 3.3, 3.4, 3.5

[SmartScholarsIndia]

Complete Records for Crossref completes the deposits OJS's Crossref plugin sends — the reference list, each author's affiliation (with its ROR ID where stored) and Crossmark — using what the journal already holds in OJS. It checks the completed file against Crossref's published schema before OJS sends it (OJS's own file goes unchanged if anything is wrong), and reads each record back from Crossref's REST API afterwards.

• Code, issues and tests: https://github.com/SmartScholarsIndia/complete-records-for-crossref (GPL v3; the test suite runs on every push)
• Release v1.0.0.5: one package per OJS line (3.3, 3.4, 3.5), reproducible builds of the tagged source; the md5s are those of the release files.
• Run on OJS 3.3.0.21 (a member journal's production site), 3.3.0.23, 3.4.0.11 and 3.5.0.5.
• Maintainer: Smart Scholars, mou@smartscholars.in
