Watch files for flow type errors

[kevinmartinjos]

I use npm run start to launch the webpack devserver. It watches my src/ folder for changes and throws compilation errors as well as linter errors.

Now I want flow type errors to appear as part of the above

AFAIK flowtype-loader only checks for flow status when I compile for the first time - not for subsequent compilations

I'm generally new to the whole webpack + flow thingy so forgive me if this can be achieved already.
