title: React Application isn't using .jsx postfix when file name includes hypens
body: <p>I have the following directory structure</p>
  
  <pre><code>src
   +actions
   +components
   +reducers
   +utils
   -views
    -app
     app-container.jsx
     app.jsx
     index.jsx
    -more-info
     index.js
     more-info-container.jsx
     more-info.jsx
    -overview
     index.jsx
     overview-container.jsx
     overview.jsx
  </code></pre>
  
  <p>Under <code>src/views/more-info</code>, if I try to update <code>index.js</code> to have the file extension <code>index.jsx</code> my build fails with <code>Module build failed: Error: ENOENT: no such file or directory, open '/Users/smcclaine/Documents/Projects/ReactReduxBoilerPlate/src/views/more-info/index.js'</code>. </p>
  
  <p>If I remove the hyphen from the directory structure and the import, it will then allow me to use the <code>.jsx</code> extension. </p>
  
  <p>Anyone have any idea how to configure my application so it will use the <code>.jsx</code> if the directory has a hyphen in it? </p>
