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.

<div class="side-block-title">
{% block block_title %}{% endblock %}

<div class="side-block-content">
{% block block_content %}{% endblock %}
