Publish to npm

[petermorlion]

#4 was merged which fixes an issue for us. But can the latest version of this repository be published to npm? The current version on npm doesn't contain this fix.

Would still like to see a new version on npm.

I'm installing directly from github (and then get smacked around a bit during code review):

npm install https://github.com/serverless/aws-event-mocks.git --save-dev

"devDependencies": {
    "aws-event-mocks": "github:serverless/aws-event-mocks"
}
