title: How to detect language with tag in Django CMS
body: <p>I'm designing the home page but there is some words that depend on the language of the actual home page.
  I want to do something like this
  {% if english %}
      Hello
  {% elif french %}
      Bonjour
  {% else %}
      Blabla
  {% endif %}</p>
  
  <p>Is there any template tag in django-cms that do the job? Thanks</p>
