ItemManager now includes a new special method to get filtered set codes from CardPool

The method is implemented in the abstract super class (ItemManager) and so inherited by `CardManager` (where there is no format nor game type that could be used), and specialised by `DeckManager`.

In particular, the only current format with limitations on sets is Brawl, and so the only one accounted for.
In any case, the list of (unique) allowed sets is automatically inferred by default from the cardpool (as in the case of `CardManager`).
It is important to note that this filter is stored into an attribute, and so the list is calculated only once.

The results of this list will be passed on the `DialogChooseSets` to update the content of the dialog panel, accordingly.
