Same-perspective console output

Previously, the board written out to the console had the 'A' and 'B' symbols switch after each move. 
This change keeps the symbols in the console output the same so that 'A' in the maze always corresponds to the score printed for player 'A' (corresponding to the bot located in the folder that was specified for the first bot), and similarly for player 'B'. 
This makes it a lot easier to follow the game by observing the console output.
Of course, the maze written to the file still switches the symbols as before.
