Fix deprecation warning caused by improper use of linkTo helper.
Fix test integration with Ember.

  - Override jasminerice's template to include an empty element to
    attach the app instance to.
  - Add `test.js.coffee` which loads the application, then configures it
    to run inside jasminerice.
  - Modify the way tests are loaded by making spec files require `test`
    instead of `application`.
  - Be explicit about uses of the run loop to isolate side-effect's to
    specific examples.
