Make it so users start out with TT cards

I think it'd be a good idea to make it so when users sign up, they get 5 crappy Triple Triad cards, enough to test out the game if they're interested in buying it.

You could do this by making a starter pack for TT in the admin CP set it to give specific cards (your crappy ones) and allow the price to be 0 (or a low number) this will let users buy that pack for free or cheap which will get them started. in future versions i think we could make it so that admins can make a TT pack a "buy once" only. so that you can purchase a pack only once (this would stop users abusing the free pack).
