Add OneShot .app

The .app happens to be a tweaked version of the one provided when
grabbing a copy of the game from Steam, as I am unfamiliar with the
process of collecting frameworks into an app bundle, at least with
cmake/qmake.  All you need to do is replace the .app in
~/Library/Application Support/Steam/SteamApps/OneShot/ to play on Mac!
