The intent of #23 was to make it possible to get the path of installed Xcodes more easily, which was implemented by #133. I realized after I wrote the description of that issue that it should be possible to both make the output nice for humans and also make it easy to pipe to other commands to get the paths for scripting purposes. This PR makes that change.
