Update option for documents and files
|Target version:||Candidate for next major release|
It would be very useful the possibility of updating documents or files in Redmine.
Beside the delete action could be a new update one.
By doing this, the attachment number will remain the same, and all references in wiki pages or issues or external places will not be necessary their change.
About the doc or file physical storage, the "replaced or updated" file could be removed.
