title: show icon in actionbar/toolbar with AppCompat-v7 21
body: <p>I tried these - but still do not see the icon like before:</p>
  
  <pre><code>getSupportActionBar().setLogo(R.drawable.ic_launcher);
  getSupportActionBar().setDisplayUseLogoEnabled(true);
  getSupportActionBar().setIcon(R.drawable.ic_launcher);
  </code></pre>
  
  <p>It seems to work when I use custom toolbar - but that would force me to touch all layouts - is there a better way to do so?</p>
