Replace awesome-typescript-loader with ts-loader in TypeScript Code Example

Since ts-loader produce much faster builds then ATL and de facto is a default webpack compiler when it comes to ts compilation it would be nice to see it used in the TypeScript Example.

Start with the TypeScript Code Example and locate where awesome-typescript-loader is configured. Review the existing loader setup and compare the expected ts-loader configuration, then verify that the example still builds successfully with ts-loader.
