[Ohrrpgce] SVN: teeemcee/8621 gfx_sdl: Add mouse wheel up/down as mouse buttons.

[James Paige]

I am surprised!

Both that this wasn't already supported, and that the wheel-as-buttons
thing was an SDL 1.2 thing. I had mistakenly assumed that the wheel was
buttons at a hardware level

I learn something new every day!

(And forget 4/5ths of it every night!)
