Fix #81: could not get paragraphs in Markdown due to the interaction between smiley and Markdown. Refactored the smilify code to use a series of regular expressions over the text when working with markdown.

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