Not showing on overflow menu
Is it possible to use the icon on overflow menu item? Here is my menu item:

``` xml
<item
    android:id="@+id/action_settings"
    android:orderInCategory="100"
    android:title="@string/action_settings"
    app:showAsAction="never" />
```

Then here is how I assign the icon:

``` java
menu.findItem(R.id.action_settings).setIcon(
    new IconicsDrawable(MainActivity.this, GoogleMaterial.Icon.gmd_settings)
            .actionBar().color(Color.WHITE)
);
```

But the icon won't appear, it works for action bar item though.

Thanks!
