Added some code to test the new reposition routines. Move the joystick left/right to adjust the X position of player 0 and up/down for player 1. Hold fire to move slower.
The topmost copy of each player is positioned using the standard reposition routines so that I could confirm the results were correct. The 2nd copy of each player is repositioned using the new routines. The remaining copies are hard coded and won't move.
I've also added the Score/Lives/Bonus kernel and am using it to display the X positions.
