Initial Support For Deploying To Cloud Foundry

Cloud Foundry is a popular open source platform-as-a-service.  The MEANJS starter project is a great starting point for developers looking to get started with the MEAN stack.  This pull request would make it easy to get the MEANJS app deployed to any Cloud Foundry PaaS.  This pull request is for the code portion only, there also needs to be some documentation on how someone would deploy the MEANJS app to Cloud Foundry.
