• Added CanonicalSlugDetailMixin mixin which allows for the specification of a canonical slug on a DetailView to help with SEO by redirecting on non-canonical requests.
• Added UserPassesTestMixin mixin to replicate the behavior of Django's @user_passes_test decorator.
• Some fixes for CanonicalSlugDetailMixin.
• AccessMixin now has a runtime-overridable login_url attribute.
• Fixed problem with GroupRequiredMixin that made it not actually work.
