If render_template get list and not id, a dict is returned.
Force the param to be a int, allow to don't use the multimode from render_template.
Avoid to get message like:
<p>{1: u'\n </p><p>Congratulation, you have received the badge <strong>Autobiographer</strong> !\n </p>\n\n'}
<p>{2: u'\n </p><p>Congratulation, you have received the badge <strong>Autobiographer</strong> !\n </p>\n\n'}
<p>{3: u'\n </p><p>Congratulation, you have received the badge <strong>Student</strong> !\n </p>\n\n'}
<p>{4: u'\n </p><p>Congratulation, you have received the badge <strong>Supporter</strong> !\n </p>\n\n'}
