Using dotenv for secret_key_base

For heroku, you'll need to:
1. rake secret
2. copy that
3. heroku config:set SECRET_KEY_BASE=<paste it here>

For local development:
1. rake secret
2. copy that
3. open a new file in your favorite editor 
4. in that file: SECRET_KEY_BASE: <paste here>
5. save file as ".env" (starts with a period)

Do not add .env to git
