Rock-Paper-Scissors

Welcome to the game of Rock/Paper/Scissors where you play against the computer. On each move the computer will choose R, P, or S, then the user will be prompted for their choice, and then the score will be updated. P beats R, R beats S, and S beats P. The score starts at 0. Add one if the person wins, subtract one if the computer wins. The game ends if the score reaches -5 or + 5. User input of 'x' or 'X' causes the game to exit.
