`stylus` module is missing when used with `stylus-loader`

[Dmitri Zaitsev]

It seems that neither stylus nor stylus-loader are installed automatically when running webpack with

// webpack.config.js
...
    loaders: [
      {
        test: /\.styl$/, 
        loaders: ['style', 'css', 'stylus']
      }
    ]
...

I had to install both modules manually to make it work.

I just tested out example/webpack1 with this:

stylus-loader installs correctly in the example, but of course stylus isn't installed automatically: it's not a peer dependency:

I'm closing this because it's not really a bug in this project. I can hook into direct dependencies of a project (e.g. import stylus from "stylus") and even peerDependencies now, but this is outside of both of those.
