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' %}
{% load forum_tags %}
{% block title %}Forums: New Topic{% endblock %}
{% block custom_js %}{{ form.media }}{% endblock %}
{% block content %}
{% forum_navigation forum "New Topic" %}

{% show_form "New Topic" form "Submit" 0 %}
{% endblock %}
