Started the round system, with emphasis on bot logic

So far bots will choose between playing a card or drawing a card depending on their perceived risk. If they choose to play a card they will decide between playing offensively or defensively based on a “Aggression” stat they are given at the start of the round.

Players can take but cannot play just yet. So far there are 4 cards, with only the shuffle card being actually usable.

Also made these badge icon templates which change depending on the difficulty (Left to right = easiest to hardest)
