Fixes bug #195:
The proper name of Apple's operating system is "Mac OS X" not "MacOS X", as can
bee seen in many places, for example http://www.apple.com/macosx/). This
contrasts the naming of the old operating system, which was called "MacOS" and
today is often refered to as "MacOS Classic".
The attached patches fixes the misuse of the name "MacOS X" in both the SDL12
and sdlweb CVS modules.
