Be consistent with "Download file"

The download section is headed "Download file" but the upload section was "Upload a file".
Be consistent - I have chosen to change to "Upload file".
Could just as easily make the download heading "Download a file".
Not sure it matters - just use the same convention in both places.

Copyright and license cleanup

- Remove personal copyright from people who assigned it to employer (ESF)

I am not sure why these lines had been duplicated, so please explain if it does something that is needed.
