Setup/add config

[Faxn]

I would have gone with require('dotenv').config()

Minor issues:

• This overwrites the existing environment. entries from config.json will overwrite the env vars from the system or command line if present. dotenv doesn't assign variables that exist.
• json != environment variables. This could potentially lead to oddness if we do something like expect an array from an environment variable because it works if we use the config.
• It's slightly more complicated and requires more explanation in the readme than the fairly standard .env format would.

That said I don't think it's worth worrying about, so of you both are happy with this approach then I'll say no more about it. If you are more comfortable with this system go ahead with it.

Added some code so they variables can't be overwritten and commented so it's easier to understand. If we are setting any env variables to an array we need to rethink how we are doing things.

I'm not a fan of adding modules for things we can easily do ourselves and I don't think "requires more explanation" is a justification to add dotenv. But if that's easier for you guys to work with, I'm ok with making the switch.
