Update to use chunkhash filename

[gingur]

If a webpack config specifies a output.chunkFilename it should be used over output.filename.

Example config:

...
output: {
    path: path.join(libPath, 'client', 'assets'),
    filename: '[name].[chunkhash].bundle.js',
    chunkFilename: '[name].[chunkhash].chunk.js',
    publicPath: '/assets/'
},
plugins: [
    new WebpackMd5Hash(),
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
      minChunks: Infinity
    }),
    new ManifestPlugin(),
    new ChunkManifestPlugin({
      filename: 'chunk-manifest.json',
      manifestVariable: 'webpackManifest'
    }),
    new webpack.optimize.OccurrenceOrderPlugin()
    ....
]

Example manifest.json before:

{
  "client.js": "client.f9f576a0309aeace48bc.bundle.js",
  "client.js.map": "client.f9f576a0309aeace48bc.bundle.js.map",
  "test-client.js": "test-client.7afae07c548189b45803.chunk.js",
  "test-client.js.map": "test-client.7afae07c548189b45803.chunk.js.map",
  "test-route.js": "test-route.328a03f54933c8bd6618.chunk.js",
  "test-route.js.map": "test-route.328a03f54933c8bd6618.chunk.js.map",
  "vendor.js": "vendor.39d04e1db2638beab3c1.bundle.js",
  "vendor.js.map": "vendor.39d04e1db2638beab3c1.bundle.js.map"
}

Example chunk-manifest.json before:

{
  "1": "test-route.328a03f54933c8bd6618.bundle.js",
  "2": "client.f9f576a0309aeace48bc.bundle.js",
  "3": "test-client.7afae07c548189b45803.bundle.js"
}

Example manifest.json after:

{
  "client.js": "client.f9f576a0309aeace48bc.bundle.js",
  "client.js.map": "client.f9f576a0309aeace48bc.bundle.js.map",
  "test-client.js": "test-client.7afae07c548189b45803.chunk.js",

  "test-route.js": "test-route.328a03f54933c8bd6618.chunk.js",
  "test-route.js.map": "test-route.328a03f54933c8bd6618.chunk.js.map",
  "vendor.js": "vendor.39d04e1db2638beab3c1.bundle.js",
  "vendor.js.map": "vendor.39d04e1db2638beab3c1.bundle.js.map"
}
