South Migrations with PostgreSQLUUIDField Create CharField Incorrectly

[brianglass]

The PostgreSQLUUIDField does not define it's own south_field_tripple() method and falls back to the one defined by UUIDField. Because of this, south migrations create these fields using a CharField type instead of a native UUID field type.

Django 1.6 support will be dropped in the next release so we can close this issue.
