Fix Django 1.11 incompatible

[alonisser]

close #277

[djtjwillia]

@alonisser looks like a couple of the builds failed, and maybe that is why this isn't merged. Would love to see this fix released though, otherwise there is no using this with Django 1.11.

@djtjwillia I don;'t think the failing tests have anything to to with the commit , but if I get a response from @syrusakbary that this is the issue I would look into it, I just didn't get any response

From the Travis logs:

  File "/home/travis/virtualenv/python2.7.9/lib/python2.7/site-packages/django/template/loader.py", line 97, in find_template_loader

    func = TemplateLoader(*args)

TypeError: __init__() takes exactly 3 arguments (2 given)

Since there are no updates to pyjade and its successor recently was deleted from pypi, I took the liberty to revive it: https://github.com/kakulukia/pypugjs

Version 5.0.1 has fixed the incompatibility with recent Django versions.
