For #235, some minor news tweaks. The submitted by text is now a link to the author's profile. Only show 1 textarea to the user when submitting a new news story. The admin can paste into the 2nd one if needed.

{% load url from future %}
{% if show_button %}
<a href="{% url 'forums-edit_post' id=post.id %}"><img src="{{ STATIC_URL }}icons/page_edit.png" alt="Edit post" title="Edit post" /></a>
{% endif %}
