Bring in a fork of ember-application as abra-application (unfortunately ember-application lacks the hooks we need to avoid having to fork)
Add ContainerView as a trivial subclass of BasicContainerView
Replace Abra (formerly SC).warn with Ember.Logger.warn
view needs layout upon appendChild
If a layer has no frame then it has no frameStyle
Pane#appendTo calls append()... should switch this around and support manually specifying which element to append a pane to, since we aim to support non-full screen apps
