Update urls.py to new urlpatterns format

[FFX01]

urlpatterns = patterns('',)

Is deprecated as of Django 1.10. I see no reason to not change it now as I tested and it doesn't seem to disrupt the function of the application at all.

Concern here might be compatibility with previous versions of Django. What about:

wrap_patterns = False
try:
    from django.conf.urls import patterns #...
except ImportError:
    wrap_patterns = True
    from django.conf.urls.defaults import patterns #...

if wrap_patterns:
    urlpatterns = patterns('', *urlpatterns)

@joshkehn Shouldn't users with old versions of Django use and old version of Swagger then?

I don't think that's an issue here as the oldest officially supported version of Django is 1.8 which uses the new way of declaring url patterns. That is, unless we want to support deprecated versions. I believe #116 is also trying to fix this same issue. I think that the solution offered there is unnecessary unless we plan to support deprecated versions.
