Changed cache system to use Django's cache mechanism. Changed field caches to make use of Django signalling instead of custom caching calls (this should make the system consistent also when called from the webserver). Created a wrapper system for easily wrapping fields with a default wrapper (so as to not have to explicitly define the properties (such as objdb.key) which all just do the same thing - load from the field and make sure to call save().
