Node properties not available

Problem/Motivation

I would like staff users to be able to update the title and body properties of a particular content type; however, these don't appear in the list of available Form Fields. I presume this is because these are node properties rather than additional fields.

Steps to reproduce

1. Create a new view of articles with the table of fields.
2. Attempt to add a new field. "Form Field Tags" will be available while "Form Field Title" and "Form Field Body" are not. ☹️

Proposed resolution

Make them available. (I don't know what would be required to do this. I haven't attempted to figure out a patch... yet.)

Remaining tasks

User interface changes

API changes

Data model changes
