Summary: NewGUI: mouse wheel support

Initial Comment:
This is an attempt to add mouse wheel support to the
NewGUI list and scrollbar widgets. (I haven't looked
much at the NewGUI code before. I hope I didn't mess it
up too badly. :-)

Of course, this means the backend has to be updated
slightly so that it will generate EVENT_WHEELUP and
EVENT_WHEELDOWN events. I only know enough to do this
for the SDL backend, and only for SDL 1.2.5 and later
since it uses the SDL_BUTTON_WHEELUP and
SDL_BUTTON_WHEELDOWN constants.

It's probably easy to support earlier SDL versions, but
I didn't see much point in doing so.
