Custom template filter to retrieve a content type of a given model instance. Useful for ModelForms which want to set the content_type field (i.e: GenericForeignKey).

A usage example:

{% load helpers %}
{% with instance|content_type as ctype %}
    <input type="hidden" name="content_type" value="{{ ctype.pk }}">
{% endwith %}
