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.
