WFileResource: errors if suggestFileName and file is empty or not found
- mime type for application
- file is empty or not found
Empty file was created using
Then Wt produces 416 (or 404 for not found) so that application state is lost.
For empty files empty downloadable attachment should be produced.
I am not sure about not found files. Maybe current behaviour is OK for them.
This bug is reproducable in Wt 3.2.3, but not in Wt 3.2.1
