How to align IconicsButton android:text with {icon} and text?
Is there a way to vertical align the icon with the text in this situation?

```
    <com.mikepenz.iconics.view.IconicsButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@style/Button.Green"
        android:text="{gmd-add} Participar"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_margin="8dp" />
```

And the Button.Green style:

```
    <style name="ANButton.Green" parent="Base.TextAppearance.AppCompat.Button">
        <item name="android:minWidth">@dimen/btn_flat_min_width</item>
        <item name="android:textAllCaps">true</item>
        <item name="android:textStyle">bold</item>
        <item name="android:paddingLeft">@dimen/btn_flat_padding</item>
        <item name="android:paddingRight">@dimen/btn_flat_padding</item>
        <item name="android:layout_marginLeft">@dimen/btn_flat_margin</item>
        <item name="android:layout_marginRight">@dimen/btn_flat_margin</item>
    </style>
```
