Title: Explain unpublished documents

Pivotal: https://www.pivotaltracker.com/story/show/37935975

Currently, editors cannot unpublish documents without it resulting in 404s.

This enables editors to provide additional information when unpublishing documents. Visitors hitting the old URLs then see this information, rather than a 404.
