Upgrade webpack-blocks to 1.0

[lightstrike]

Would address this issue raised by @PolyPik and is generally a good idea 😄

Oh, I missed the mention from @andywer there.

Before upgrading webpack-blocks here we need to update the three custom blocks we are using:

• webpack-blocks-split-vendor
• webpack-blocks-happypack
• webpack-blocks-server-source-map

So they will work with the new webpack-blocks API. Once we do that, it should be easy to update ARc.

I'm very busy these days. PRs are very much appreciated.

UPDATE: webpack-blocks-happypack v0.2.0 works with webpack-blocks v1 thanks to @boxfoot.

I think that was the hardest one.

2 blocks to go now. 😊

UPDATE: webpack-blocks-split-vendor v0.3.0 works with webpack-blocks v1

Only one left. And that seems to be the easiest one.
