*8859* Improve article copyright/license affixing

PR for testing and comment; Do not merge.
Any defaults are choose are likely to be wrong for at least half the community, but IMO it's better than nothing. OTOH I'd suggest assigning copyright to the journal on upgrade, and as part of the release notes I'll include a warning about the changes in operation around permissions. For year, either issue or article publication dates would be OK for me; it sounds like your group prefers issue publication dates, which is OK with me.
