Title: issue 315: config locale fall back to english in production environment.

This is my solution to issue 315.

Testing
Manual:
1. Comment out an entry in /config/locales/fr.yml, "welcome_to:" for example.
2. Run Markus in dev mode, go to http://0.0.0.0:3000/fr and note that fall back doesn't happen on the login page("translation missing").
3. Run Markus in production mode(rails s -e production) and go to http://0.0.0.0:3000/fr
4. Fall back to english("Welcome to MarkUs!")
