use module.rules instead of module.loaders for webpack2

[marcofugaro]

modules.loaders was renamed in modules.rules in webpack 2, here are the docs

Would be easier when adding custom loaders, to merge the with the default loaders.

Here is the line I'm referring to https://github.com/andywer/webpack-blocks/blob/master/packages/webpack2/index.js#L78

Also the example in the README needs to be updated.

It's on its way. 1.0 release will be webpack 2 only and use module.rules 😉
See #134.

Duplicate of #111

Sorry for the slow progress on 1.0, though!

Nice!
