Subject: [PATCH] Small fixes to the namespace_list template helper

The `namespace_list` helper is used to filter YARD objects in order to populate
search lists. The code was originally derived from the `class_list` helper.
This patch guards against calling `children` on objects that have no children
and removes a recursive call to the old `class_list` method.
