Title: add more specific definitions for Rx.Observable.fromEvent

e.g. ```fromEvent(element: Node, eventName: "click", selector?: (arguments: any[]) => MouseEvent): Observable```

Users will get proper typing when subscribe to the Observable without having to add type information. Addresses issue https://github.com/borisyankov/DefinitelyTyped/issues/3246.
