Clone model mixin

Add this as a superclass of any Django model to allow making copies of instances of that model: class Entry(models.Model, CloneableMixin): [...] e = Entry.objects.get(...) e_clone = e.clone() e_clone.title = 'Cloned Entry' e.save() The new object is saved during the clone process and ManyToMany relations are copied as well.
