Subject: [PATCH] [FEATURE] ember-testing-checkbox-helpers

fixes #9798 (https://github.com/emberjs/ember.js/pull/9798#issuecomment-69384792)

When test driving, `click` and `unclick` are useful for ensuring the
state of a form.

```javascript
export default DS.Model.extend({
  title: DS.attr(),
  body: DS.attr(),
  isDraft: DS.attr("boolean", defaultValue: false)
});

test("doesn't publish posts in draft mode", function() {
  fillIn("#title", "this post is hidden");
  fillIn("#body", "this won't be displayed");
  check("#is-draft");
  click("#submit");

  andThen(function() {
    equal(find(".post:contains('this post is hidden')").length, 0);
  });
});
```

`check` and `uncheck` allow the test to remain unchanged if the
`defaultValue` of `isDraft` changes from `false` to `true`.

The test only cares that:

* when `click("#submit")` executes, the `#is-draft` checkbox is `checked`
* `isDraft` is true
