title: Webpack babel-loader isn't reading .babelrc (supporting old browsers)
body: <p>When I run babel by itself it reads the <code>.babelrc</code> and transpiles as expected. However, when I run webpack with <code>babel-loader</code>, the outputted code is very similar to the original code, but I would like for it to work in older browsers.</p>
  
  <p><strong>.babelrc</strong></p>
  
  <pre><code>{
      "presets": ["env"]
  }
  </code></pre>
  
  <p><strong>webpack.config.js</strong></p>
  
  <pre><code>module.exports = {
      entry: __dirname + '/src/index.js',
      output: {
          filename: 'bundle.js',
          publicPath: '/dist',
          path: __dirname + '/dist'
      },
      module: {
          loaders: [
              {
                  test: /\.js?/,
                  include: __dirname + 'src',
                  loader: 'babel-loader'
              }
          ]
      },
      devServer: {
          inline: true,
          port: 8080,
          historyApiFallback: {
              index: 'index.html'
          }
      }
  }
  </code></pre>
