4.1 Nav / Menu - custom style class

[PrettyPixels]

I'd love to see an option to add a custom class to menus (and menu items) in the nav. This would allow us to easily target a specific nav item and style it differently from the others. Very helpful if you'd like a specific nav item to stand out (such as a donate button).

It looks like this is possible in the desktop view, but not on mobile.
