Update to latest master for ember-data and ember.js.
Move apiNamespace off of Catalog.

Ember.Object.create no longer supports definition of computed
properties.  I could do something like

  App = Ember.Application.extend
    apiNamespace: ...

  window.Catalog = App.create()

but I get the vibe that what Ember apps Should Really Do is not modify
the application object at all.  Fair enough.
Remove custom transforms.

With the array type now gone, I won't be needing this anymore.
