Rejection should be propagated.

Queue allow to control the execution of a list of promises.
Especially, it can cancel the list of promises.

The queue is fulfilled only when all pushed promises are fulfilled.
It gets the latest push promise fulfillmentValue as result.

    var queue;
    queue = RSVP.Queue();
    queue.push(function () {
      return 1;
    };
    queue.push(function (value) {
      return value + 1;
    };
    queue.then(function (value) {
      assert(value === 2);
    };

Cancel all sub promises as soon as cancelled.

Cancel allow to manually interrupt a promise execution.
The promise becomes rejected with a CancellationError.

var xhr, promise;
promise = RSVP.Promise(
  // Resolver function
  function (done, fail) {
    xhr = new XMLHttpRequest();
    xhr.open("GET", url);
    xhr.send();
  },
  // Canceller function
  function () {
    xhr.abort();
  },
)
promise.cancel();

Fix npm integration

version bump

fixing tests for rethrow in IE 6,7,8 as well as phantom/node

Rsvp#rethrow

Rethrow makes sure that any exception in your promise chain won't
swallowed:

getJSON('/posts.json')
    .then(handlePost)
    .fail(RSVP.rethrow)

You can also to chain it further, like so:

getJSON('/posts.json')
    .then(handlePost)
    .fail(RSVP.rethrow)
    .then(null, handleRejection)

adding promise#fail

- toString.call([]) angers IE, use Object.prototype.toString instead
- getPrototypeOf polyfil

toString.call([]) fails while the Object.prototype.toString.call([]) works
