Primary and secondary items looks the same

[beprogressive]

<color name="material_drawer_primary_text">#FF0000</color> changes colors of primary and secondary text items.
<color name="material_drawer_secondary_text">#00FF00</color> change nothing.
And in generally, secondary and primary items visually do not differ from each other.

@Remie-l the Primary Item has a different height and the icon is smaller.

You can see it. just see the sample application.

about the color. you are right. the current version has a small bug. will be fixed in the next version
