[Composite.Versioning.ContentVersioning] Hard to undelete pages with the same page titles (usability)

[wwwysocki]

Because pages are logged under the page titles in the content modification log, it is hard to distinguish between them when undeleting them, for example.

And pages may have the same page title (but different paths). Also, when you duplicate a page, you also get a page with the same title as the original.

Repro:

1. Duplicate a page.
2. Delete the original page.
3. Delete the duplicated page.
4. System > Content Modification Log > View Log
5. Locate the deleted pages.
6. Try to restore only one of them (either original or duplicated)

Expected: You can tell one from the other and easily restore the one you need.
Actual: Both pages have the same page title and it's hard to tell which one is original and which one is duplicated.
