Add {{array ...}} helper

[kellyselden]

It seems it would be a perfect companion to the {{hash ...}} helper:

{{hash
  name="parent"
  children=(array
    (hash
      name="child1"
    )
    (hash
      name="child2"
    )
  )
}}

It would probably get the most use in component integration tests, but could be useful in normal templates as well. Taken from here.

I created Ember pirate for that helper. It is the only addon that can work without being installed :) https://github.com/Serabe/ember-pirate

This seems very natural to me. 👍
