No issue
- Prevent download count ajax request from running forever, even after setup is complete.
- Remove unneeded setup routes and controllers.
- Refactor to use ES6-imported ajax.
- Refactor to use injected services.
No Issue
- Switches to the newer style of dependency injection.
- Instead of injection Controllers via "needs," use
Ember.inject.controller().
- Get rid of initializers that were only injecting objects
into various factories. Converts these objects into Ember.Service
objects and declaratively inject them where needed via
Ember.inject.service(). The added benefit to this is that it's no
longer a mystery where these properties/methods come from and it's
straightforward to inject them where needed.
