Williams WPC (Alpha Numeric)

+ Note: It is possible to get funhouse (fh_l3 at least) in-game by coining it up, then holding the following keys,
+ and pressing the start button, or else you get "PINBALL MISSING":
+ W (right ball shooter, c6 r2)
+ E (right trough, c6 r3)
+ [ (dummy jaw opto, c5 r1)
+ ] (right outlane, c5 r2)
+ \ (right slingshot kicker, c5 r3)
+ It's possible not all of these are strictly necessary to make it work.
+
+ TODO: replace the 8x8 pinball input matrix keymap by some sort of common interface for the williams system 6, 9, 10, 11 and wpc_an;
+ while the actual purpose of the switches differ per machine (and some machines like wpc_an have one switch permanently closed as a test switch),
+ the entire matrix should be mapped to keyboard keys, there are more than enough keys on a 104 key keyboard to do it, even avoiding MAME's reserved keys.
