The 3-click launch can only run in us-west-2

[osvaldsson]

There is a limitation in Lambda where the code needs to be served from a bucket in the same region as the Lambda function resides. We currently have the default build code deployed in us-west-2 only which requires a deployment to be made there if you use the "Launch Stack" link in the README.

This limitation does not apply if you run your own development version using your own bucket.

There is a workaround in the README now, but we need to implement a permanent solution.
