Williams System 11B: switched to use the Williams D-11581 "Audio Board" device instead of its own implementation. Document the switches needing to be held to get in-game in all of the System 11B pinballs. Fill out the remainder of the System 11B switch matrix to allow all 64 possible switches to be hit.

    Williams System 11b

    Known issues:
-    - Background music is not working in some games
    - Black Knight 2000 sometimes goes nuts or resets, although this is largely dependent on
      whether the 'ball 1' animation was played or not.

      Proximate cause is smashing the stack, after which the RTS at 61DE (in bk2k_l4)
      transfers to 0000 (where no valid code exists).
    - Black Knight 2000 LG-1 set reports U26 ROM FAILURE. Bad/hacked dump or original bug?
