uploaderDelete fails when using CloudFront

[jamgold]

The easiest way to setup CloudFront is to name the bucket after the CNAME of your CloudFront URL, which results in S3 URLs like

http://s3.amazonaws.com/<BUCKET>/testing/rt2ngHzJHTysi6CqK.jpg

where BUCKET is the CNAME like s3.domain.com

Unfortunately the uploaderDelete method takes the entire S3 URL as an argument and then tries to create a relative URL from that to pass to Knox by using url.split(/.com/)[0], which fails to provide the correct relative url because the S3 url contains more than one .com, and the Knox.remove fails, yet the method reports back success.
