- Make the controller part more readable and more efficient (O(1) ORM
operations instead of O(n)) and remove deprecated code.
- Add the possibility to have a toggle standalone option. This is
used as soon as an `<opt/>` is alone in its container (note that now,
the container can be any tag and will be ignored during rendering).
- If an option has no specified 'string' to attach to it, the name of
the first view it toggles will be used.
