Title: update doc for ArrayController

The example for `ArrayController` uses `{{#collection}}` in the template.

Since it looks like `each` and I using `collection` made me run into [an issue](http://stackoverflow.com/questions/9234401/collection-using-contentbinding-does-not-automatically-update-when-rendering-in), I updated the doc to use `each`.
