title: Material-ui response to breaking change in React 15.4.0? "Cannot resolve module 'react/lib/EventPluginHub'"
body: <p>React v 15.4.0 was released this morning and seems to have included a change that broke react-tap-event-plugin v1.0.0 producing this error:</p>
  
  <pre><code>$ npm build
  &gt; myProject@0.1.47 build /.../myProject
  &gt; node scripts/build.js
  Creating an optimized production build...
  Failed to create a production build. Reason:
  Module not found: Error: Cannot resolve module 'react/lib/EventPluginHub' in /.../myProject/node_modules/react-tap-event-plugin/src
  </code></pre>
  
  <p>(note: I cleaned up the output a little)</p>
  
  <p>According to <a href="https://github.com/zilverline/react-tap-event-plugin/issues/85">THIS react-tap-event issue log</a> version 2.0.0 of react-tap-event fixes the build problem.  However, material-ui is still using react-tap-event version 1.0.0.  What are the options here?  The only options I can think of are:</p>
  
  <ul>
  <li>Downgrade react and other packages as described in the link above</li>
  <li>Wait for Material-UI to upgrade to react-tap-event 2.0.0</li>
  </ul>
  
  <p>Any other solutions here?  I'm pretty much dead in the water if I wanted to use react 15.4.0, as far as I can tell.</p>
