bitbake: toaster: address Django-1.10 API deprecations

There are four main API deprecations in Django-1.10:
  (a) String view arguments to url() must be replaced by
      the explicit class reference
  (b) New TEMPLATES stucture in settings.py consolidates
      TEMPLATE_DIRS, TEMPLATE_CONTEXT_PROCESSORS,
      TEMPLATE_LOADERS, TEMPLATE_STRING_IF_INVALID, and
      TEMPLATE_DEBUG
  (c) patterns() wrapper in url() is removed, with
      urlpatterns now a simple list
  (d) NoArgsCommand in commands() must be replace by
      BaseCommand, and handle_noargs() changed to
      handle()

Also, the Django version checker must be updated to accept
two digit sub-version numbers (e.g. "1.8" < "1.10")
