Adding a "prefix" to taxonomy

Right now there isn’t such thing as a taxonomy archive page (which is a little goofy), thus Breadcrumb NavXT doesn’t generate a breadcrumb for the taxonomy name. If you want to manually add it in, you will need to hook into the bcn_after_fill action.

As it’s parameters, one will be the bcn_breadcrumb_trail object. Within this object is a member variable called trail (in 5.0 this is renamed to breadcrumbs, though trail still exists as a link to it). bcn_breadcrumb_trail->trail is an array of bcn_breadcrumb objects. You will want to inject a new bcn_breadcrumb object into the second to last slot in the breadcrumb trail.
