... by additionally keeping local (currently non-owning) pools per
"interesting" type.

Current situation:
  - The global object pool does not scale well for looking up
    objects, as iteration plus qobject_cast typically iterates
    over all pooled objects.
  - User code that can use typed results from the object
    pool need to have access to the full type definition anyway,
    i.e.  depend on the plugin of the target class anyway.

The patch here solves the scaling problem is to have local
type-specific pools to which objects register in their
constructors and deregister in their destructors.

This patch here does *not* change the ownership model of the
pooled objects, however, it opens the possibility to change
the ownership model per type (e.g. by not putting things into
the global pool at all anymore and make the local pool 'owning')
and the intent is to handle that in later patchs.

Even without the follow-up patches this here is a performance
improvement for the cases that access the local pools instead
the global one, i.e. "practically all".

The default "matches" method now takes the widget and looks for all
child labels, checkboxes, push buttons and group boxes.
Because of that, the former "createWidget" method
can be called multiple times without creating a new widget
(-->widget()), and the "finished" method must ensure that the created
widget gets deleted, since not all widgets that were created are added
to the UI anymore.
