Road to 2.0.0

[jasonmit]

Incomplete

• Reverse the argument behavior of format-message
  • {{format-message 'path.to.foo.bar'}}
  • {{format-message (icu '{{population, number, integer} as of {census_date, date, long}}')}}
• Warn with message when intl-get is passed a key that is not found (Can't get message translations in non-template code #107)
• ember-browserify the intl deps
• Provide a migration document with thorough instructions explaining upgrade path for breaking changes.

Completed

• Move format message into its own formatter
  • Move the format computed prop out of service (mostly complete, format-message is last one)
• Remove defaultLocale. Instead, declared in env configuration (the same config evaluated at build time)
• leverage instance-initializer for injecting instead of initializer
• Tests failing due to new addition of registry in the container. Will require changes to moduleForIntl
• YAML translation file support
  • JSON translations are already supported, I'd like to support both for 2.0
• When a translation is merged in from the default locale's translation file, throw a console warning at build time with the key(s) missing (mostly done, needs verifying for edge cases)
• BREAKING: Translations now hang off translations (root folder) instead of app/locales
  • Allows to easier side-loading of translations
  • Reduces confusion between the three terms: locale, cldr, message/translation
  • Part of Rewrite translation "resolver" logic #67
  • Commit: dd8b808
• Automatically merge application default locale to all translations at build time
  • Configuration of default locale is defined in EmberApp within config/environment
  • Reduces confusion around fallback/default locale logic
  • Part of Rewrite translation "resolver" logic #67
• BREAKING: Translation files can be in two formats, json and yaml, instead of ES6 modules
  • JSON supported
  • Allows for easier third-party service serving translation assets
  • Commit: 411ea11
• BREAKING: Translation modules no longer contain messages object. All translations hang off the exported parent object by default

Other

• Move formatting logic out of service and into formatters. This will thin the service, and the service will simply proxy to the formatters
• Remove support for 1.9 (Handlebars)
• BREAKING: Intl service is now only injected via Ember.inject.service, no longer automatic as it's seldom needed and Ember now makes it convenient to inject services
• ES6-ify

Updated to reflected the YAML translation format proposal

@jasonmit Is it possible to get out a beta1 before we complete some of the icu / path switching?

Trying to avoid our team getting a surprise at some point. Sadly we are still tracking this branch (/sadpanda) and then in beta2 release the switch?
