For #95. You can now make posts with no text in the body if you have attachments. And now if you create a new topic with an attachment, and the POST fails (say you forgot the topic title), we will now re-attach attachments. Also fixed a bug in the smiley code that would arise if it was asked to markup an empty string.

{% extends 'weblinks/base.html' %}
{% block title %}Web Links: {{ link.title }}{% endblock %}
{% block weblinks_content %}
<h3>Link Details: {{ link.title }}</h3>
<dl>
{% include 'weblinks/link.html' %}
</dl>
{% endblock %}
