Can we make the auth file fetchable by an environment variable as well?

Hi,

Is it possible to also allow the contents of the auth file to be loaded from and environment variable?
.env allows this json content like this: GOOGLE_AUTH='{}

Since we're running on heroku, and we don't want the auth credentials to be in the repo, we don't want to use the regular way of setting GOOGLE_APPLICATION_CREDENTIALS or saving the information to the database/project config.

I just pushed this for the next release due next week.

1.4.0 is out with now with this feature. Keep in mind you'll have to properly escape newline characters in the RSA key.
