Currently, it seems impossible to use TypeScript type mapping for templateUrl and even styleUrls which is a bit odd since it seems to me that TypeScript should be resolving all paths?

Repro steps

• Add a path map to tsconfig.json compiler options: "paths": { "@core/*": ["core/*"] }
• Use a mapped path in a component's templateUrl property: templateUrl: '@core/forms/login-form.component.html'
• ng serve --aot

Observed behavior

ERROR in : Couldn't resolve resource @core/forms/login-form.html' from /ng-cli/src/app/home/login-form.component.ts

Desired behavior

The TypeScript path mapping works as expected like everywhere else, and the templates are found and compiled.
