HUGE thanks to @mixonic and @rwjblue for all their help with Ember helpers! This release wouldn't have been possible without that work.

• Support Ember 1.13.1+ and 2.0+. Note this release is not compatible with v1.13.0 and never will be.
• Stop auto-injecting service:i18n into Components, Controllers, and Routes. Clients should instead use i18n: Ember.inject.service() as needed.
• Fix Spanish spelling.
• Fix {{t}} helper with dynamic keys.
• Add locale blueprint
• Use Ember.Helper if available (Ember >= 1.13)
• Use Ember.Service if available (Ember >= 1.13)
• Remove dependency on Ember.EnumerableUtils.map as that will be removed in Ember 2.0.
