Typo in "SFML and Xcode (Mac OS X) tutorial

[KRMisha]

In the "System Requirements" section of the tutorial, one of the bullet points is "An 64-bit Intel Mac with Lion or later (10.7+)" instead of "A 64-bit Intel Mac with Lion or later (10.7+)". It probably creeped in there when someone must have added the "64-bit" precision.
