Basic wrapper around aws-sdk

Wraps aws-sdk in a very simple and naïve way.
- configure AWS credentials in config/development.js (use
config/sample.js as a template)
- specify the service name as the first arg (fe: S3)
- specify the command name as the second arg (fe: listObjects)
- specify all command parameters as double-dash args (fe: —Bucket
myBucketName)
Provide sample, and add own config to .gitignore

I’m not sharing my AWS account with the world, no!
