Combine app collection files with models.

I don't really like having separate files for the
collection and model classes, so I'm combining them
in one file and exporting as object properties.

Essentially the same thing I'm doing with the view classes.
Active resource base controller, views.

- Since most of the controllers will be implementing the
  same CRUD functionality, I made an upstream ResourceController
  class for them to extend.
- Aggregated the apps base item and collection views into a
  single definition file
- Added an abstracted 'itemEdit' view for the app that implements
  the usual form submission and model event listener methods.
