Title: You know you gotta love that C++11

A cross platform method of sleeping for all compilers which support C++11. So gcc 4.6, VC11, and maybe some others should all work fine with this.
You'll have to define SFML_CPP11 somewhere, like in the config, or through cmake maybe.
My goal is to replace all the Impl stuff in System with C++11 implementations.
Feel free to modify this commit as needed to make it conform to your standards.
