investigate the usefulness of and update/replace table columns of docs/packages.md

Investigate whether or not the table columns in docs/packages.md need to be kept, removed, or added to.

As part of this investigation, clearly define each column's definition to be less ambiguous and easier to test/validate a package against.

Each column should be investigated individually and scored for its own usefulness in terms of whether or not it brings value to this document. Table columns with poorly rated value should be removed and any additional lacking table column headers should be added as appropriate.
