Fix problem when deleting multiple topics from a forum in bulk. We getting a list of topics from the database, then deleting each topic. But after you delete a topic, the forum.last_post on the remaining non-deleted topics can be stale. This was causing a weird DoesNotExist. Now just get the topics one at a time from the database.

{% extends 'weblinks/base.html' %}
{% block title %}Web Links: {{ title }}{% endblock %}
{% block weblinks_content %}
   <h3>{{ title }}</h3>
   {% if links %}
   <dl>
   {% for link in links %}
      {% include 'weblinks/link.html' %}
   {% endfor %}
   </dl>
   {% endif %}
{% endblock %}
