* feat(@angular/cli): update schema to match new `sourceMap`
* feat(@angular-devkit/build-angular): fine grain settings for sourceMaps
This PR add more control over which sourceMaps you want, Now you can enable sourceMaps for scripts only, styles only or both. Also we added another functionality which are hidden sourcemaps. These are normaly used for error reporting tools.
