feat(core): update to Angular v6.x.x and higher

BREAKING CHANGE: `forRoot()` on `NgwWowModule` has been removed as no longer necessary

Before:

```ts
import {NgwWowModule} from 'ngx-wow';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgwWowModule.forRoot()],
  bootstrap: [AppComponent]
})
export class AppModule {
}
```

After:

```ts
import {NgwWowModule} from 'ngx-wow';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgwWowModule],
  bootstrap: [AppComponent]
})
export class AppModule {
}

 ## Installation

 Install above dependencies via *npm*. In particular for `WOW JS`, run:
 ```shell
 npm install --save wowjs
 ```

 >**Note**: If you are using `angular-cli` to build your app, make sure that `wowjs` is properly listed as a [global library](https://github.com/angular/angular-cli#global-library-installation), by editing your `angular-cli.json` as such:

 export class AppModule {

-Other modules in your application can simply import ` NgwWowModule `:

-@NgModule({
-  declarations: [OtherComponent, ...],
-  imports: [NgwWowModule, ...], 
-})
-export class OtherModule {

 ## Usage
+
 Once the module is imported, you can use the `NgwWowService` in your component (i.e. `AppComponent`) to trigger reveal animation by calling `init()` or to be notified by WOW when an element is revealed.
