Cards

Adds deck/card/hand items for playing card games. Pretty rough around the edges and could use some helper functions but it works. Didn't add any instance on the map to not make merging maps pain in the ass.

\obj\item\toy\card - Single card.
\obj\item\storage\deck  - Deck
\obj\item\toy\cardhand - Card hand helper object to make avoid lots of cards lying around.

Probably missed something obvious when making this so point out any problems.
