Add a new API to ListView: setGestures(int). This allows developers to enable gestures to jump inside the list or filter it. This change also introduces a new XML attribute to control this API. It also adds the ability to theme the GestureOverlayView from the gestures library. Finally, this adds a new VERSION header to the binary format used to store the letters for the recognizer.
