Changelog

• Add deprecation for quoteless outlet names ({{outlet main}} should be {{outlet 'main'}}).
• [BUGFIX] Update the Ember.Map#forEach callback to include the map being iterated over.
• [BUGFIX] Ensure that tagless container views are rendered properly.
• [PERF] Ember.View#_outlets is no longer observable.
• [PERF] Avoid extending a view for every {{each}}.
• Ensure initializers have a name property (provides a helpful assertion if missing).
• [BUILD TOOLING] Enable easier cross-browser testing by publishing builds and tests to S3.
• Enable Ember.run.join to return a value even if within an existing run loop.
• Update Ember.EventDispatcher to use Ember.run.join. This is required so that synchronous
  events (like focus) do not spawn a nested run loop.
• Deprecate context switching for of {{each}}.
• Deprecate context switching form of {{with}}.
• Add improved error message when a component lookup fails.
• Ensure that component actions that are subscribed to, trigger an assertion when unhandled. Consider the following example:

{{!component-a.hbs}}

{{some-other-component action="saveMe"}}

Clearly, component-a has subscribed to some-other-component's action. Previously, if component-a did not handle the action
it would silently continue. Now, an assertion would be triggered.
