title: new ActionBarDrawerToggle when using AppCompatActivity
body: <p>Today Google updated the AppCompat library to version 22.1.0, and we can now use <code>AppCompatActivity</code> instead of <code>ActionBarActivity</code>.
  This means we no longer need to have a <code>Toolbar</code> view in our activity layout.</p>
  
  <p>The problem is that in order to create a Drawer toggle button, I cannot use <code>new ActionBarDrawerToggle</code> anymore, because it expects a <code>Toolbar</code> parameter, which will not exist.</p>
  
  <p>How am I supposed to add the toggle button to the ActionBar now?</p>
