Fixing #107. Apparently some signal handlers were getting connected twice (double import?) and thus saving a forum post would cause 2 email notifications to go out to the post topic's subscribers. Use the dispatch_uid parameter in the connect call to work around this issue.

.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%;
}
