title: Material-UI React does not recognize the `underlineStyle` prop on a DOM element
body: <p>I have followed the example code for styling the underline color of a material-UI <code>TextField</code> element.</p>
  <p><a href="http://www.material-ui.com/#/components/text-field" rel="nofollow noreferrer">http://www.material-ui.com/#/components/text-field</a></p>
  <p>However when I try to add my own style, react cannot recognize this property.</p>
  <pre><code>&lt;TextField type=&quot;number&quot; id=&quot;Commission&quot; label=&quot;Commission&quot; underlineStyle={{borderColor : orange500}} fullWidth /&gt; 
  </code></pre>
  <p>I get the following error message in the chrome developer console</p>
  <pre><code>warning.js:33 Warning: React does not recognize the `underlineStyle` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `underlinestyle` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

  <p>npm view material-ui version
  0.20.0</p>
  <p>I have confirmed that this property exists on the <code>TextField</code> element.</p>
  <p>I am using the Jumbo React theme, and all of the underline colors of the <code>Textfield</code>s default to purple.</p>
  <p>Not sure why my custom style does not override the <code>TextField</code> underline color.</p>
