Made some tweaks to the ajax login javascript. Cleared the inputs on failure so someone won't repeatedly try a bad login. Redirect on lockout so the page will refresh. Set focus on the username box after failure for convenience.

.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%;
}
