Taxonomy_browser: subcategory nodes visualization

The default behaviour of the taxonomy module is to visualize (and count) only the selected category nodes, and not the subcategories nodes.
To change this just modify a line in the taxonomy_browser.module , taxonomy_browser_page_submit function:

$a = array('taxonomy/term/'. $str_tids, (isset($node_type) ? 'type='. $node_type : ''));

becomes

$a = array('taxonomy/term/'. $str_tids."/all", (isset($node_type) ? 'type='. $node_type : ''));
