Move operation should also invoke hook_taxonomy

The 'update' case for hook_taxonomy is never called in taxonomy_manager_form_move_submit(). Simple fix is to call module_invoke_all when looping through the moved terms. Patch to come.

foreach ($selected_tids as $selected_tid) {
    $term = taxonomy_get_term($selected_tid);
    $term_names_array[] = $term->name; 
    module_invoke_all('taxonomy', 'update', 'term', (array) $term);
  }
