Add 'Artifact Id' column (which is basically extension id or profile id or value set id, etc.) on the artifacts page

[Rdhanoa90]

Change the artifacts rendering to be a table with 3 columns with the heading "Title, Artifact Id, Description" where title and description correspond to what's there now and Artifact Id will be the extension id (or profile id or value set id, etc.) I.e. we'll do this for all artifact types.
