pkp/pkp-lib#2072 Working prototype of versioning based on new publica…

…tion entity

This commit includes all of the initial work done to support versioning based on a split between submissions and publications. All submission data related to publication, such as title, abstract, citations, authors and galleys, has been moved to a new publication entity.

Submissions have a "one to many" relationship to Publications. Each Submission may have one or more Publications attached to it. Each Publication is treated as a new version. Published version data can not be modified.

- New publication entity split from submissions
- New API endpoints for publications
- Workflow UI changes to support versions (publications)
- Pre-publication validation checks
- New STATUS_SCHEDULED for publications scheduled for publication in a future issue
- Deprecated many methods on the Submission object
- Upgrade scripts written from 3.1.x.
- Tests updated to work, except for issue import.

Some code is commented out or has not been updated yet. Progress on remaining support for versioning will be tracked in Github.
