Heavy petting for the contextual component RFC

@mmun for you to consider.

👍 I could definitely see several places in our we could use this.

One question, what about proving class references, rather than strings, to the component helpers. For private component classes? For example:

// app/components/special-button.js
var MyPrivate = Ember.Component.extend({ /* ... */ });

export default Ember.Component.extend({
  myPrivateComponent: MyPrivate

  /* ... */
});

{{!-- app/templates/components/special-button.hbs --}}
{{!-- passed by class, not string --}}
{{component myPrivateComponent}} 

We've got a lot of components in our app that aren't used in block form and have "private" sub-components. It gets kind of messy to have every component in it's own .js file sometimes.

I was secretly hoping to see some mention of a splat-like-operator, but I realize it's probably outside the scope of this RFC.

@workmanw splat is being discussed at handlebars-lang/handlebars.js#1050 We're waiting for wycats to clear his stack. Hopefully we green light soon :-)

@mmun has concerns about how we handle the container (and therefor injections etc) on bare classes. I think it may be surmountable. If he is hesitant I would at least like to get the un-controversial version of this rolling so we can land it soon, maybe 2.2 if core approves on Friday.
