v7 release - Angular v5 Support

[e-schultz]

• Update to Angular 5 compiler
• Update RxJS, change to use let-able operators
• Requires @angular-redux/store 7+

Breaking Change

• NgReduxRouterModule now needs to be imported with .forRoot

before

@NgModule({
          declarations: [AppComponent],
            imports: [
                RouterModule.forRoot(appRoutes),
                /* .... */
                NgReduxRouterModule  ],
                  bootstrap: [AppComponent]
                  })
export class AppModule {}

after

@NgModule({
          declarations: [AppComponent],
            imports: [
                RouterModule.forRoot(appRoutes),
                /* .... */
                NgReduxRouterModule.forRoot()
              ],
                bootstrap: [AppComponent]
                })
export class AppModule {}
