create-react-app support TypeScript now!

I think we should remove create-react-app my-app --scripts-version=react-scripts-ts because the new create-react-app version support TypeScript.

But it's not released yet right? Heard it would be in version 2.1 of CRA?

CRA uses babel transpiler which still has some important limitations, so as it is right now CRA won't replace react-scripts-ts in general case.
