Not showing taxonomies associated to more than 1 custom post type

When a taxonomy is associated to more than one post type, it doesn’t show up in the filters list. This happens because of how wp_filter_object_list works (used by get_taxonomies). I’ve come up with a workaround that suits my needs, use it freely if you want to.

I’ve replaced the original tc_ctf_get_filters function with these two:

function tc_ctf_exclude_builtin($tax){
    return $tax->_builtin == false;
}

// Get only the custom taxonomies associated with this post type
function tc_ctf_get_filters() {
    global $typenow;

    $taxonomies = get_object_taxonomies($typenow, 'objects' );
    return array_keys(array_filter($taxonomies, 'tc_ctf_exclude_builtin'));
}

Thanks for this plugin!
