title: Only display tabs in action bar
body: <p>I've just used ActionBar Sherlock to implement the android action bar on pre 3.0 android devices. I'm having one issue when I'm using tab navigation though.</p>
  
  <p>Currently the action bar is devided in two rows at the top of the screen. The first row contains the app icon and app title, while the second row contains my navigation tabs. I tried to remove the top bar with actionBar.setDisplayOptions(0);, but now i still have two rows, but the top row is empty. How can I remove this top row?</p>
  
  <p>Thanks!</p>
