The issue was that I had set the ctor to set the p/t to 0/0 rather than
-1/-1. This meant that when you join a game in progress (spec or
reconnect) the server would send the card value to the client as 0/0,
instead of -1/-1. The client has been coded so that if the toughness is
<0 then dont show it. 0/0 is instead shown.

We still need to look into cards with no p/t being set to a 0/1 as
@tooomm mentioned in anther issue. As it stands, this is more important
than that.

Addresses issue from #934

preliminary AlwaysRevealTopCard support related to issue #31, server code cleanup (finally removed getGameState)

optionally destroy tokens on zone change; added multi arrows; card menu changes; arrow fixes; initial commit for attachCard code
