Add documentation stub for Ember.Router

Adding /** @scope Ember.Router.prototype */ makes YUIdoc print out the
entire router definition, without any error message. It doesn't actually
blow up, it just prints source. It's strange.

The method listing don't seem right yet -- it contains methods like
Ember.Route#controllerFor. But it's a start.

Make sure destroy tests actually do something
Fix issue with Metamorph replace

Scenario: Two nested {{if}}. Outer true, inner false.
Step 1: Set inner to true.
Step 2: Set outer to false in same runloop.
Result: Children of the inner conditional are created without being
destroyed.
Expected: Children should not be created at all.

"Observerable" is not a word in English
{{#each}} should retarget if bound to controllers
Adds itemController to {{each}}
CollectionView no longer respects emptyView defined on the View.
This updates the test to show that the functionality is broken.
This does still work if you pass the emptyView as an argument via handlebars collection helper
'''{{#collection App.ListView emptyViewClass="App.EmptyView"}} ... {{/collection}}'''
And the {{else}} still works.
Make the CollectionView test more robust.
{{#each itemController}} should actually work

This attempt works by creating a private
array controller for the EachView to use, and
treating that as its content.
