Document Manager; dragging an Outlook email to Logs may overwrite an existing file

Dragging an Outlook email to the Log page of an Account, Client etc may overwrite an existing file in the Document Manager.

An email's Subject is used as the file name, so if two emails have the same subject the second one would overwrite the first one.

Now if the file already exists the date and time is appended to the end of the file name.

Note, in addition, the message box shown after a file is saved in the Document Manager is now shown as a Notification.
