Removed getSurveyResponseFromPost from Surveys helper.
We will use the power of Django Forms instead of getting our own properties. This fits better into the rest of Melange which also uses this approach.
<html>
<head></head>
<body>
<h1>Django Internal Tests: Login</h1>
{% if form.has_errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
<form method="post" action=".">
<table>
<tr><td><label for="id_username">Username:</label></td><td>{{ form.username }}</td></tr>
<tr><td><label for="id_password">Password:</label></td><td>{{ form.password }}</td></tr>
</table>
<input type="submit" value="login" />
<input type="hidden" name="next" value="{{ next }}" />
</form>
</body>
