title: Ionic (pluginName: statusbar) does not exist, can't change statusbar font color
body: <p>I was having trouble changing the font color on the status bar in an ionic / cordova iOS app to white despite following having the statusbar plugin installed:</p>
  
  <pre><code>cordova plugins
  ...
  org.apache.cordova.statusbar 0.1.8 "StatusBar"
  </code></pre>
  
  <p>and in app.js</p>
  
  <pre><code>.run(function($ionicPlatform) {
    $ionicPlatform.ready(function() {
      if(window.StatusBar) {
        StatusBar.styleLightContent();
      }
    });
  })
  </code></pre>
  
  <p>and in config.xml</p>
  
  <pre><code>&lt;preference name="StatusBarOverlaysWebView" value="true" /&gt;
  &lt;preference name="StatusBarStyle" value="lightcontent" /&gt;
  </code></pre>
  
  <p>The font color wasn't changing from black and I was getting error messages in the XCode console:</p>
  
  <pre><code>CDVPlugin class CDVStatusBar (pluginName: statusbar) does not exist.
  </code></pre>
  
  <p>for reference, my cordova version is <code>3.5.0-0.2.6</code> and ionic <code>1.0.0-beta.13</code></p>
