Dropdown nested menus

You can add nested submenus by inserting a .dropdown.dropdown-submenu as an item inside a .dropdown-menu, because we're just reusing the same classes to create each nested submenu, there's no limit to how many steps you can get, and it comes optimized for mobile devices too :D

You can change the style of one or all dropdown menus to a dark version.
