Moved winner determination to separate function isPlayerWinner() in BattleState
-Before displayingResults(), player is given gold if they won the battle
-Gold no longer given in exit()
BattleResultDisplayState now displays 5 profileStats, 5th being player's current gold amount
-Added function getGold() to ProfileManager the returns gold
