Proper player cards

Player cards can be created for any player (not just hard-coded to the
premier league). Additionally, the stats are specific to the selected
team and competition instead of being for that player generally. This
also means that dates are no longer hard-coded for the stats since
they use the selected cmopetition's start date.

Also pulled out the FutureZippers, certainly one of my sillier ideas
ever.
Add appearances to player cards
Goal Keeper -> Goalkeeper in player cards

PA was giving us the former, we want to show the latter.
Remove goals against from defence player card

We seem to only ever get 0 through for this so it isn't useful.
