Title: Polymorphic attributes

These are changes I completed in early July. In the code they show up as "Property" stuff. Note that they have a pretty solid test suite. Note also that we should have @sashax look at this---I created this before he did his work on informal cart creation, so there is almost certainly some overlap. However, the informal cart creation stuff could be dropped out ---it is the "PropMixin", the data migration, and the tests that matter.
