Deck verification for Dunwich investigators

[jayelbird]

For Dunwich investigators, show an error if there are greater than 5 off-class cards included in the deck.

Another issue is that Rex Murphy isn't allowed Fortune traited cards, but nothing stops them from being added.

Reworking the definition system for deck options, then the db should enforce the restrictions better (especially for Marie Lambeau)

I think the deck verification restriction may currently not be in place. Choosing a core investigator defaults to showing only cards from their classes, but it doesn't hide cards they can't play if you expand which classes are being shown or if you show 3-5 xp for their off-class.

Valid cards for investigators should now be fixed, the data for the limits is there I just need to make it detect if you are over the limit.

[Kamalisk]

should respect all deck limits correctly.
