docs: Tries to load a custom template tag set. Non existing tag libraries
      are ignored.
  
      This means that, if used in conjunction with ``if_has_tag``, you can try to
      load the comments template tag library to enable comments even if the
      comments framework is not installed.
  
      For example::
  
          {% load friendly_loader %}
          {% friendly_load comments webdesign %}
  
          {% if_has_tag render_comment_list %}
              {% render_comment_list for obj %}
          {% else %}
              {% if_has_tag lorem %}
                  {% lorem %}
              {% endif_has_tag %}
          {% endif_has_tag %}
