Hide Empty Categories
---------------------

Cleans up the category list on the thumbnail pages by hiding those
categories that are empty, regardless whether they really are empty or
whether the current user just sees them as empty. Benefit is to avoid
end-user confusion with empty categories when they do not have access to
anything within them.

Potentially this plugin may conflict with themes that customize
theme_display_cat_list(), as we customize that, too.
