(In the future) Rename MongoHQ references to Compose

[diagramatics]

Found this article when deploying my app.

Heroku hasn't renamed the references of MongoHQ (the addon name, the CLI reference, etc.) but this should be considered and a separate branch should be ready to merge to the master branch when that happens.

@diagramatics your link is asking me to create an account with Compose, do I need to do that to read an article?

@JaKXz Well, I guess that link is just for MongoHQ current users only. Have a look at http://mongohq.com and see where it got redirected to. That'll be easier.

Thanks, that's what I was looking for. I signed up for a compose account, but I was just wondering aloud for those who didn't :)
