Super-Rogue: fix some out-of-range constants. Constants K_ARROW etc., for causes of death other than monsters, are in the 240-255 range. They were often passed to functions taking char, which is usually signed, making the values out of range. The function declarations have been changed to unsigned char, which is also the type used by the scoreboard code.
