[Catalyst] Base controllers and multiple inheritance

[Zbigniew Lukasiak]

I would say don't use Catalyst::Controller::HTML::FormFu in that case
- the functionality it provides is rather basic.

By the way I am also working on a FormFu based CRUD Catalyst base
class (continuation of Catalyst::Example::InstantCRUD).  Looks like it
has become fashionable thing recently.
