Documents created by copy author and creation date

Documents created by copy have different creation dates:

• in the History, the creation date is the date at which the document is pasted (makes sense since the event is "created by copy")
• on the Summary tab, the creation date and author are the ones from the original document

One can expect that the pasted document will be modified and that the original document is just a basis. So the pasted document is a new document and should have new author (the user who pasted it), new creation date and new contributors.
