Increment the version to 0.4.0-SNAPSHOT
Upgrade to the latest aws-java-sdk (1.8.9.1)
Attempt to fix up the region detection for #5

We try 3 different methods:

1. Parsing directly out of the URL that is being used (this seemed broken for s3:// URLs)
2. Doing a DNS lookup of <bucket>.s3.amazonaws.com and then reversing the resulting IP to see if it has a region in it.  I think this was working at one point but they seem to be using different hostnames now so I'm now trying to regex extract the region.
3. Using the AmazonS3Client.getBucketLocation call to determine the region.  This only works if the AWS credentials have access to the getBucketLocation call which is why it's last.
