Added
- The `enable remember me` configuration directive.
Changed
- The `repr()` of a `DAList`, `DADict`, or `DASet` is the `repr()` of
its elements, and `repr()` triggers the gathering process.
- The `.salutation()` method of the `Individual` object now uses the
optional attributes `.salutation_to_use` and `.is_doctor`.
Fixed
- Problem with `exclude` on a manual list of choices.
- Lack of curly quote in "I don't know" buttons.
- JavaScript error introduced in 0.2.23 that interfered with `hide if`
functionality.
