Added a custom tag to display a link to a profile. Refactored the avatar tag to optionally display a profile link around the image. Removed the width and height attributes from the avatar image tag. I think this was causing disk hits whenever those properties were not cached. The avatar tag is now an inclusion tag.

<div class="smiley_farm">
{% for s in smilies %}
<img src="{{ s.image.url }}" alt="{{ s.code }}" title="{{ s.title }} {{ s.code }}" />
{% endfor %}
</div>
