Add argument to register_taxonomy to specify which post type(s) show up on Tax archive

[sc0ttkclark]

Right now, taxonomy archives only show the default post post type in their archives. However, it would be greatly useful during register_taxonomy() to specify exactly which post type(s) should appear under the associated taxonomy archive.

So this would touch register_taxonomy() to set the argument, and WP_Query to make use of the argument when setting the default post type for the query to use (if one has not been specified).

I'm sorry, I was mistaken in my initial creation of this ticket. This only applies to custom post types associated with the Category and Post Tag taxonomies. I'll have to open a new one, as (custom) taxonomies already have this functionality based on associated objects.
