Fixed an SDL issue where it would dereference a Window's erroneously, and an issue where SDL was being shut down twice. I added a CMake Feature which allows controls over the build with a simpl series of check boxes.
Merge branch 'master' of github.com:BlackToppStudios/Mezzanine
 Had to fix CPU arch bug, I just used a dirty hack, but it should be easy to expand
