Title: content-deletion - a few UI commits

The UI work for content-deletion is still in progress; however, submitting a pull request to our branch now, rather than waiting and having a single huge pull request.

Refer to the list of commits for details on what is included. In general, includes creating changesets of type 'deletion' or 'promotion', changes to the content tree to handle adding/removing content to a promotion or deletion changeset, a couple of bug fixes...etc
