about feature #2845, the autonomous fragment displayAttachedFiles.jsp have been improved :
- Fragment is no more displayed for users when there is no attached files
- DragNDrop can be explicitly disabled by setting new 'dnd' parameter to false
when operationPane is not displayed, creation actions area is still visible
Now, this area is hidden by default and visible when at least one action of creation is available
