title: TEMPLATE_DIRS is missing in settings.py (django 1.6)
body: <p>I am reading <a href="http://www.djangobook.com/en/2.0/chapter04.html" rel="noreferrer">http://www.djangobook.com/en/2.0/chapter04.html</a> which follows Django 1.4 but I use Django 1.6 so how to set the template directory in Django 1.6 as settings.py doesn’t have TEMPLATE_DIRS variable and why the developers changed this?
  Thanks in advance.</p>
