Support for RxJS 6

I’m submitting … [x] Feature request

Current behavior

Using RxJS 5.5.x imports like import { Observable } from 'rxjs/Observable'; are used.

Expected behavior

RxJS 6 brings simplified imports like import { Observable } from 'rxjs'; … so it is necessary to import all classes from directly rxjs.

What is the motivation / use case for changing the behavior?

The problem is the size of a bundled application when the application is using RxJS 6 and a package is using 5.5.x because it is necessary to use rxjs-compat package and load both of them.

Other conditions

If all places in code where angular-modal-gallery is using RxJS imports are manually rewritten to new RxJS import style, everything works so it seems that this change would be very easy to done and the only question is how to manage and publish this package for RxJS 5.5.x and RxJS 6.x in parallel.

Environment (the most important section to fill very carefully)

Angular 6.0.0-rc.3
RxJS 6.0.0-tactical-rc.1

@Ks89 … ah, sorry. You are right. It was really version 4.0.1.
