[patch from Kelvin Delbarre] SDL's Quartz video implementation maps command

Browse Source 
clicks to right-clicks and option-clicks to middle-clicks, a feature intended
for Mac users with single-button mice who are running SDL-based games that
require a multi-button mouse. This is unhelpful in SheepShaver, where we want
command-clicks and option-clicks to be passed through unchanged to the emulated
Mac OS. We can disable the unwanted behavior by setting an environment variable
SDL_HAS3BUTTONMOUSE intended for this very purpose.

A similar change in main_windows.cpp is NOT required, because only the Quartz
video implementation is involved.

By SDL convention, putenv is used in preference to setenv, although for Unix
platforms it doesn't matter.
