How to specify different TS configs depending on environment

[bnheise]

Hey, thanks for this great template! I was wondering how I could specify which tsconfig file to use, though. I have different configs based on whether I'm building for development or production, but I don't see here how I could tell webpack which one to use. With the standard ts-loader, i can do this:

 options: {
 	configFile: 'tsconfig.prod.json',
},

I can't seem to figure out how to do that with this setup.
