Update typescript block to work with webpack 4

[s-h-a-d-o-w]

I'm using webpack-blocks to provide configuration to react-styleguidist and experienced the following errors.

TypeError: resolver.ensureHook is not a function

I've resolved it locally by using this configuration and updating the versions of awesome-typescript-loader and typescript to the latest ones. (The latter just to get rid of most deprecation warnings)

If you want me to, I'll prepare a PR for this.

Hey @s-h-a-d-o-w, thanks for reporting!

Which version of webpack-blocks are you running? The v2 prerelease?

[s-h-a-d-o-w]

You're welcome. :)
Yes, I am using 2.0.0-alpha.

Cool. Yeah, a PR would be appreciated :)
