- break up the code base into one file per component
- extract persistence into a separate module
- general cleanup

- Never mix spaces and tabs.

Emberjs routing

* refs/heads/master-temp:
  Minor list revisions

`TodosController` will filter the content based on router's filter.

Most of the non-dynamic (from routing point of view) views should reside in application view.

Renders items on root path.

TODO: Refactor this to be part of `ApplicationView` as child views.

Initialize entries controller upon application creation, to be passed later as content property.

Cleanup `Ember.CollectionView` template, on editing use a contextual view.
Fix race condition issue with focusOut/insertNewline when editing last item.
