Introduce the ability to restore a trashed post as a draft

[johnbillion]

Given a post in the Trash, it's impossible to determine the previous status of the post. This has an impact when considering whether to restore it.

A situation can occur where a published post gets trashed but needs to subsequently be restored after first making corrections to it. This workflow is not possible because restoring the post will restore it to its previous status, which is published.

Some enhancements that could be made to the Trash listing screen to help:

• Append the previous status to the post title, similar to how the status is shown next to non-published posts on the main post listing screen.
• Introduce a way to restore a trashed post as a draft, regardless of its previous status. A good way to achieve this might be with a Restore as Draft link that's shown alongside the existing Restore link.
• After restoring a post, add an Edit Post and/or View Post link to the 1 post restored from the Trash confirmation message so the user can quickly navigate to the editing screen without having to search for the post again.

All of the suggestions sound great (and shouldn't be that hard to do)! Lets add them :)

Not quite a dupe, but consolidating this with #23022.
