Title: Simplified Ember.RadioButtonGroup implementation

This PR contains the same API as #755 but has a simper implementation. `Ember.RadioButton` can also be used independently of `Ember.RadioButtonGroup`.

Also introduces Ember.Control which is a view that uses itself as its context, necessary for the `Ember.RadioButtonGroup` implementation.
