Retain the Original Create Date on Attachments despite Edits to FileName, Comment Type, Content Type, or Page location

Currently, when an attachment is edited, Confluence updates the Date and loses the original create date. This is very misleading since only descriptive data has changed - the original file has not (and cannot be) changed.

When dealing with attachments, the date the file was loaded is what is really important. The original creation date should therefore be retained and displayed in the Attachments Macro listing. Minor descriptive changes such as the filename, comments, and page location that can occur months or years later should not overwrite this basic information. Microsoft Windows recognizes this importance in its own conventions - you can change the file name, move the file, and even copy the file without affecting the file date.

In a recent Confluence version update, this distinction was recognized in a change in the way Confluence handles the creator field - Confluence used to just replace the Creator with the name of the editor but now puts the modifier's name after the original creator in parenthesis if its different (see screen print).

That convention could be extended to include the date. The original create date should be retained and the modified date should be put into the parenthesis, i.e. John Doe (last modified by Jane Doe on July nn, nnnnn).

The attachment macro should also be changed to:
1. Show the original Creator with the modifier in parenthesis (with wrapping so it doesn't take too much column space).
2. Show the original Create date

Finally, when the only action is to change the page the attachment is on, the Creator parenthetic should be changed from "modified" to "moved" (moving is not a significant modification).
