Added configurable computer player - use 'com=random', 'com=minimax' etc as cmd-line args.

Default is AlphaBeta.
Updated ActionListener for UserChooserFrame so that selecting from the list (or typing a new name and pressing RETURN) also triggers the action.
Added the player and computer algorithm names to the title bar e.g. "Bob vs. Alpha-Beta".
