title: use holo theme on Android < 4.0
body: <p>I'm developing an app for Android 2.2 and higher.
  I use the great ActionBarSherlock (thank you, Jake Wharton !!) to use the action bar on pre-ICS devices. </p>
  
  <p>While the actionbar looks great, all other gui elements have the look of the default theme of the device (in my case HTC Sense 3).</p>
  
  <p>Is there a possibility to style my (>= Android 2.2) app on all android devices with the Holo.Dark.Theme?</p>
  
  <p>I compile my app with Android 4.0.3, the minSDK version is 8.</p>
