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.

{% load url from future %}

{% load smiley_tags %}
{% load bio_tags %}
{% avatar user 0 "left" %}{% profile_link user.username %}:<br />{{ msg|safe }}
