[Feature Request] Menu Item ID as class name on MegaMenu

[ryanbelisle]

I noticed in the MegaMenu, the Item-ID isn't written out in CSS like in the Joomla Core Module. It be great if we could get that into the MegaMenu so it would be consistent and allow someone to target those individual menu item's via css. This class would be added in addition to the other ones present on the LI tag already.

<li class="item-ID"><a>...</a></li>

At the moment, you have 2 options to target individual menu item in css.

1. Add a class for those menu items. Megamenu allow you add extra class for menu item, submenu or column. The extra class is better used than the item-ID class.
2. Each menu item has a property data-id="ID", therefore you can use selector [data-id="ID"] in css to target the item.
