feat: restructure the template to match Angular web project structure (#86)

The following changes are in this PR:
- the app folder is renamed to src as is in the web Angular projects.
- @nativescript/schematics is a devDependency and angular.json file is added. This allows the developers to start using the Angular CLI immediately after creating a project.
- App_Resources are now at root level.
- nsconfing.json file is added.

depends on NativeScript/nativescript-dev-webpack#633 and NativeScript/nativescript-dev-typescript#61
