gh-795 Migrate to Angular 6

* Convert configuration files from `.angular-cli.json` to `angular.json`
* Move E2E tests to `e2e/src`
* Move Protractor configuration files to `e2e` folder
* Refactor error handling classes due to stricter type-checking of generics
* Add `rxjs-compat` to avoid having to refactor RxJs to use pipeable operators
* Fix deprecated RxJS usages
* Update Readme
* Update Flo to `0.8.0`
