* Switch the "Play" button to check for "Play HabitRPG"
* Change "#register-tab" selector to use "#registrationForm"
* Increase delay when only running protractor specs, to ensure the server has
time to spin up
* Repair broken e2e test introduced in 8d03cfc (copywriting change was not
reflected in the spec)
* Updated i18n.coffee code to be more cautious (it expected the 'en' locale
would always be available, but provides appropriate error handling as-is).
* Extended timeout duration for protractor, as registration was slightly above
30s.
* Added karma-mocha-reporter as a dev dependency to ensure test visibility.
