Instantiate a ViewState's view if it's not already an instance

[devinus]

E.g.:

  var viewState = Ember.ViewState.extend({
    view: Ember.View.extend({
      elementId: 'test-view'
    })
  });

[tchak]

why calling destroy on the view? What happens then I return to this ViewState?

[wagenet]

@devinus, @tchak seems right, I have some doubts.

[devinus]

@tchak the view is created again. Destroying the view will ensure that bindings aren't being run on the view when it's no longer being used and the view can GC.

[tchak]

Yes if it is a class, but if I set view to an instance?

[devinus]

@tchak I've reverted my change destroying the view on exit for now and rebased. Hopefully by whittling down the changes in this pull request it'll be easier to evaluate it's merits.

I am ok with this. Can you rebase against master?

[devinus]

@wycats Done.
