added two more templates for displaying admin login form and admin logout message.
{% extends 'base.html' %}
{% block content %}
<a href="/task/claim/tid={{task.id}}">click here</a> to return to the claims page.<br /><br />
Select a user to assign this task.<br />
<form action="" method="POST">
{{form.as_table}}
<input type="submit" value="Assign Task">
</form>
{% endblock %}
