Icon + Text not centered?
I have the following: 

```
<com.mikepenz.iconics.view.IconicsButton
    android:id="@+id/facebookLogin"
    android:theme="@style/Button_Facebook"
    android:text="{faw-facebook} Log in with Facebook"
    android:textAllCaps="false"
    android:layout_below="@+id/textView2"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="16dp"
    android:layout_width="wrap_content"
    android:layout_height="56dp"
    android:textColor="@android:color/white"
    android:textSize="20sp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp">
</com.mikepenz.iconics.view.IconicsButton>
```

The icon doesn't seem to be centered with the text. Is this something wrong with my implementation or a bug? The padding also doesn't seem to apply. Any help is appreciated!
