S3 bucket policy to whitelist access to CloudFlare (IPv6 addresses don't seem to be supported in bucket policies)

Created an AWS forum thread noting that IPv6 addresses are broken: https://forums.aws.amazon.com/thread.jspa?threadID=149144

I updated the IPv4 range of CloudFlare here https://gist.github.com/ZE3kr/0f26ae62f1590338a3f1f0127289f7d6
