Updating logic

1) Added enum updated GameBoard from char[,] to enum[,]
2) Added new properties to Player
3) GameBoard now sets sign per given indexes, with issues thrown.
4) GameManager can make a player move and check for wins

Question:
1) sending struct by val, do I need to add ref or not?

Left to do:
1) r_GameBoard - to Array so we can use clear?
2)… ?
3) switch players in playGame
4) Add winning notification and asking if player wants to continue.
5) Check coding standarts.
