Title: [feature] Nested submenus for top menu in protostar

# Description
This enables protostar to display nav-pills menus with two or more levels of submenus.
# Testing instructions
1. Create a menu with more than two levels in backend or use one of the ones provided with sample data. In my pictures, I used the "About Joomla" menu from sample data.
2. Create a menu module
* Type: Menu
* Position: position-1
* Select Menu: Your menu from step 1
* Start level: 1
* End level: all
* Show Sub-menu Items: Yes
3. Save / publish the module.
4. Set Protostar as your frontend template.
5. Hover over the menu items in frontend. The first level of sub-items will be shown, but nothing beyond that.
6. Apply the PR
7. Now, all levels should be accessible in the dropdown menu.
