RxJS Release v2.2.16

Minor fixes from RxJS v2.2.15 to include bug fixes and changes to Enumerable to make it ES6 compatible.

From Iterable

This release has a new function which makes it ES6 compatible with iterables. We now have Rx.Observable.fromIterable method which takes in an iterable and converts it to observable sequence.

var set = new Set([1,2,3]);
var observable = Rx.Observable.fromIterable(set);

var subscription = observable.subscribe(console.log.bind(console));
// => 1
// => 2
// => 3

Bugs Fixed

1. #122 - changed fromGenerator to fromIterable
2. #123 - fixed Promise detection which was picking up on Join Patterns.
3. #124 - same as above
