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

[Ralph Versteegen]

Hahah.
It seems SDL 1.2 can't tell you the distance the wheel scrolled, especially
since that also depends on OS sensitivity settings, which is why they
rewrote how it works. Plus SDL2 supports scrolling on a touch screen.
At a low level, mice might well return button presses.

I've been wanting to add mouse wheel support in some places in Custom for a
long time.
