Support for rxjs 6

[yashsriv]

Angular 6 uses rxjs 6 which doesn't have deep imports supported.

@yashsriv thanks for the notice, i'll add this as a note to myself:

https://github.com/ReactiveX/rxjs/blob/master/CHANGELOG.md#breaking-changes-6
deep imports: Can no longer deep import top-level types such as rxjs/Observable, rxjs/Subject, rxjs/ReplaySubject, et al. All imports should be done directly from rxjs, for example: import { Observable, Subject } from 'rxjs';

Now that Angular 6 is officially released I am going to do the modifications this weekend.

Thanks for looking at this so quickly after Angular 6's release.

I've found this article useful for upgrading from RxJS 5 to 6: https://auth0.com/blog/whats-new-in-rxjs-6/
