For bitbucket issue #2, tweak the admin settings for the Post model to reduce slow queries. Define our own queryset() method so we can control the select_related(), and not have it cascade from post to topics to forums to categories. Removed 'topic' from list_display because MySQL still sucked with 2 inner joins. Now it seems to be tolerable with only one join to User.

{% load url from future %}
{% load bio_tags %}
{% if avatar_url %}
<a href="{% url 'bio-view_profile' username=user.name %}">
<img src="{{ avatar_url }}" alt="{{ user.name }}" style="float:left;margin-right:3px;" /></a>
{% endif %}
{% profile_link user.name %}:<br />
{{ user.message|safe }}
