Allow serialization of model methods

[Marc Garcia]

It will be useful if model methods could be serialized. For example:

in model...

class Person(models.Model):
    first_name = models.CharField(max_length=32)
    family_name = models.CharField(max_length=32)

    def full_name(self):
        return '%s %s' % (self.first_name, self.family_name)

...when serializing...

data = serializers.serialize('json', Person.objects.all())

...doesn't include full_name, even if specified in fields.

Serializing methods isn't really possible in the generic sense, since a method could require arguments. However, serialization of properties (which can be implemented as methods), and serialization of any other model property has been accepted as a proposal - see ticket #5711.
