Make file(DOWNLOAD) fail on http error 

If a http server responds with a result code greater than 400 then the
data returned from the download probably do not match that expected.
Teach file(DOWNLOAD) to fail with an error in this case instead of
silently pretending that the download worked.  The file(UPLOAD) command
already does this.
