taught ai when not to play a planeswalker, told ai to look for planeswalkers as a card type to play.
fixed a crash related to tokens and cardgui..tokens dont have models....
made a 1 line change to deckveiwer that makes it usable on touch devices and improves the overall look and feel of deckveiwer....
