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.

.poll-form {
    padding-bottom: 1em;
}
.poll-form ul {
    list-style: none;
    padding-bottom: 0.5em;
}
.poll-form li {
    padding: 0.5em 0 0.5em 0.5em;
}
dl.poll-result {
    width: 80%;
}
