AWS Nuke

This was shaping up to be a really nice Node.js implementation of deleting all resources in an AWS account, but then I found rebuy-de's aws-nuke.

Currently supports APIGateway, CloudFormation, CloudWatch, DynamoDB, Lambda, SNS, and SQS. The EC2 directory was next on my list; it currently contains templates to implement.

Requires the use of AWS_PROFILE environment variable to select the account in ~/.aws/credentials to use.

Open sourced in the hope this will help somebody else who needs this for Node.js. PRs welcome.
