[FSPA] Cross-platform configuration tool for LED OCD

[Edan Grossman]

Wow, that is dedication!  I'll try out your tool (for windows) when I get
my next game.

I am glad to see that I am not the only one who appreciates LED OCD boards
and has customized the lighting profile with the config tool.  (Using the
config tool is completely optional, the default profile built-in to the
board is perfectly fine.  The config tool is for those who are extra OCD
about the lighting behavior and wants to fine tune it to their preference.)

For those who swapped out incandescent bulbs for LEDs and do not have an
OCD board, you should get one, especially for the Stern Whitestar era
games.  It will make the LEDs fade on and off nicely, just like the
original incandescent bulbs did, and it will eliminate the ugly LED
flickering that occurs on many older games.  IMO this is the best mod you
can install, other than a colordmd.

Btw, my Hot Hand is sold, but my T3 and Metallica are still available.
Both of those games have color displays and the LED OCD board.
