Fix for Microsoft Windows Shutdown/Restart

Restores the portion of code that shuts down and restarts Windows, a 5 millisecond delay was added but it's not guaranteed that ES will be able to gracefully shutdown by the time Windows does.

You need to unpack SDL2_mixer-2.0.4-win32-x86.zip onto your ES folder.

Build based off @jrassa's repo + the new features from @fabricecaruso's repo.
