Make external version of 'typescript.js' match 'typescript.d.ts'.

![ts-services](https://cloud.githubusercontent.com/assets/199519/5478009/741fc258-85fe-11e4-9be2-d17ec280f6be.png)

The downside of my patch is ''typescript.js' is a duplicate of 'typescriptServices.js'. The symmetry with typescript.d.ts is useful for testing/using the latest language service with node and getting auto-complete etc...
