Title: Arrayproxy itemcontroller

This a proposition based on #1664 but using container api

This implementation obviously have a few problems :

* I had to introduce a dependancy on `container` to `ember-runtime`, I do not think we want it.
* The whole `removeObject` think is busted. Not sure what the solution is.
