Fixing #138. Shoutbox scroller breaks down if there aren't at least 2 things to scroll. Added some dummy shouts on the client side if the shout database is empty.

<div class="smiley_farm">
{% for s in smilies %}
<img src="{{ s.image.url }}" alt="{{ s.code }}" title="{{ s.title }} {{ s.code }}" />
{% endfor %}
</div>
