Malcolm Tredinnick 29050ef999 Fixed #5420 -- Added support for delayed loading of model fields. ...

In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.
