Add a system for easily reproducing a production environment.

Dockerfile is the initial step for this.

Afterwards: #135

@natebrennand What's the infra strategy for deploying webhooks?

[natebrennand]

@brishin, would you like to be in charge of maintaining the Docker file / w/e deployment tool for Courses or do you want me to be? If you, what's the status on the Docker file?

[brishin]

I can write the initial Dockerfile, but we'll need more tooling around it to bring everything up automatically. @natebrennand, I'll leave that part to you?

[brishin]

Also for reference, my current deploy method: forever stopall && meteor bundle --directory ~/Courses-bundle/ && ~/run_courses.sh
