We need to do this in the models.py files, otherwise the post_save signal
might not be connected right away on launch of the application. Move them
over there, add a dispatch_uid so it only gets hooked up once, and do some
other function moving around so we don't have circular imports.

This allows caching the results of an arbitrary function and its arguments
in the Django-managed cache, e.g. memcached in production.
