Allow for multiple versions of metadata for a given dataset. DRAFT, RELEASED, DEACCESSIONED, etc.

Versions implemented as Draft and Released. Deaccessioning will be handled in a future development phase.

Tested on 4/7

Tested basic version states: draft/released, major/minor versions and forced major with file upload.

Found an issue with apparently being able to edit older versions and opened a separate ticket.
