Database configuration works with Cloud9
Database configuration works with Cloud9

- add: IP environment variable in database config
- change: test database is controlled by legislative_twitter user
          because Cloud9 had a password set for user postgres

Side effects: a IP variable will need to be added to any development
system/.env file.
