Some paranoia checks for buggy decks when evoking or stacking them.

If the deck has no cards left yet still exists, the deck is destroyed and Nemelexites are awarded a brownie point for using up a deck. If a stacked deck has holes in it, the holes are removed. If a stacked deck has buggy cards in it, they are discarded. If a deck had problems with it, the user is asked if s/he is sure about using the (now fixed) deck, and no turns are used if the answer is "no".
