Made most of my agreed changes. Got pot amount working and cards now
grey out correctly when a player has folded. Also fixed pound signs
(hopefully) Did not manage to add multiple rounds, I think we may need a
fairly major rewrite of Round (most likely removing the static stuff) to
get it to work properly. We could have a reset function but that seems
more like treating the symptoms than an actual fix. I think we should
discuss what to do tomorrow.
