Zack Middleton 30fcabec65 SDL Mouse Button clean up
Make 'b' variable an int so that key values more than 255 will work (not currently an issue in ioq3 afaik).
Use SDL_BUTTON_* for easier transition to SDL2.
(SDL2 doesn't have SDL_BUTTON_WHEELUP or SDL_BUTTON_WHEELDOWN, X1/X2 are different values.)
