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 'base.html' %}
{% block title %}{{ flatpage.title }}{% endblock %}
{% block content %}
<h2>{{ flatpage.title }}</h2>
{{ flatpage.content }}
{% endblock %}
