Compatibility with Amazon S3 and CloudFront

I have raised a pull request to allow this plugin to be used with https://www.ads-software.com/plugins/amazon-s3-and-cloudfront/

https://github.com/mansj/enable-media-replace/pull/15

Would be great if this could make it to the next version ??

Thanks
Iain
