Support for directories in on-disk apps.  
Support for directories in on-disk apps.  

Notes:
* Currently set to traverse only up to 5 levels deep to avoid infinite loops (e.g., symlink a directory to itself  like //routing.site.freebase.dev does)
* Will also skip any directory (and its descendants) if it has a .metadata file as it's presumably itself an app (likely a version)
