Title: Making s3credentials optional

If credentials are supplied, use them. Otherwise the AWS SDK will attempt to resolve credentials in the following order:

Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
Java System Properties - aws.accessKeyId and aws.secretKey
Instance Profile Credentials - delivered through the Amazon EC2 metadata service.
