un-verbose

• Due to a PR in CLI 7.3.0-beta.0 and @angular-devkit/build-angular 0.13.0-beta.0, we don't need to switch the CLI into verbose mode when using an array of webpack configs like we did in ngx-build-model. For this, the newest ngx-build-modern checks the versions installed of those packages.

• ng serve accepts now a --verbose switch and ngx-build-plus prints out the modified webpack config when used.
