Support download of files identified as abusive

[cyberduck]

@dkocher created the issue

Files identified as abusive (malware, etc.) are only downloadable by the owner. Additionally, the query parameter acknowledgeAbuse=true must be included to indicate that the user has acknowledged the risk of downloading potential malware. Your application should interactively warn the user before using this query parameter.
