Update TicTacToeApp

Major overhaul of methods. 1.1 version heh

fixed playerNumber bug where selecting player 2 wouldn't allow player 1 a turn ever. 

fixed validation logic for playerNumber so it cannot be anything but 1 X or 2 O, upper and lower limits

fixed validation for alreadyUsed spaced on the game board (had put check for X and Y instead of X and O, duh)

fixed validation logic for gameBoard to ensure all entries are within the range of the 3x3 board, upper and lower limits 

removed some test String outputs used in testing previous bugs

removed duplicate calls to setToken that were in the validation subroutines to ensure all validation tests are run before setToken gets ran
