feat(typings): updated typings for combineAll, mergeAll, concatAll, switch, exhaust, zipAll

[david-driscoll]

Description:

This adds support for nested observables using some of the newest features of the TypeScript
compiler. Things like like the following that were impossible before will now work correctly!

const source1 = Rx.Observable.of(1, 2, 3);
const source2 = [1, 2, 3];
const source3 = new Promise<number>(d => d(1));

let result: Rx.Observable<number[]> = Rx.Observable
      .of(source1, source2, source3)
      .zipAll();

// or

let result: Rx.Observable<number[]> = Rx.Observable
  .of(source1, source2, source3)
  .pipe(Rx.operators.zipAll());

Also updated tests in related areas.

I'm just curious if this fixes issue like this #2759 or this #3290.

[david-driscoll]

@martinsik looking at those issues, yes it will.
I hadn't gone through the issue list yet to find any open issues that would be fixed, I was just fixing errors round in the unit tests (which aren't currently compiled with strong types).

Thanks @david-driscoll!
