Removed FinancesBaseView in favour of mixins.
This removes the close coupling with the shared app.
Formatting for conventions compliance.
Correct login redirect URL.
Fixed LoginRequiredMixin to inherit from object.
This way it's not an old-style class, which was not intended at all.
Basic RealAcct details page.
Pushing more context data to template for RealAcct detail view.
Getting objects is delegated to mixins; refactored accordingly.
This is very similar to using SingleObjectMixin and MultipleObjectMixin,
but has the added benefit that more than once mixin can be used in the
same view.
