Updated to a supported idmapper version. Added a method for calculating the cache usage of the idmapper, and tied it to the @system command.

This fork of django-idmapper fixes some bugs that prevented the idmapper from
being used in many instances. In particular, the caching manager is now inherited
by SharedMemoryManager subclasses, and it is used when Django uses an automatic
manager (see http://docs.djangoproject.com/en/dev/topics/db/managers/#controlling-automatic-manager-types). This means access through foreign keys now uses
identity mapping.
Tested with Django version 1.2 alpha 1 SVN-12375.
My modifications are usually accompanied by comments marked with "CL:".

Because the system is isolated, you may mix and match SharedMemoryModels with regular Models. The module idmapper.models imports everything from django.db.models and only adds SharedMemoryModel, so you can simply replace your import of models from django.db.
