Add a named CSS class in addition to the numeric class

This module’s great. Thanks!

When using references, numbers aren’t very useful to me unless they are ordinals based on names that I'm managing or if they're used for arithmetic, so the name that came up for one of my menu_block menus, menu-block-3 was problematic. Besides not being easy to remember or associate with its purpose while styling CSS, it can change. Consequently, I modified the module to also create a named class in addition to the numeric class name.

I also had styling problems trying to override id (#) selectors, so I added an option to create a CSS ID, too. To take advantage of that capability, you’ll need to update your menu-block-wrapper template file to match the change in this patch.

You can associate the styling among block submenus by giving them all the same class name, but you’ll need to change the template to remove the CSS ID.
