> This patch does 3 things that makes sub-classing RawLocalFileSystem easier.
> First, it adds a constructor that allows a sub-class to avoid calling getInitialWorkingDirectory().
This is important because if a sub-class has an initially null uri (prior to initialize()
being called), then getInitialWorkingDirectory() will cause a NullPointerException when it
tries to work with the FS's uri.
> Second, allows subclasses to modify the working directory.
> The third thing this patch does is change loadPermissions to not pass the URI object
to the File(URI) constructor, but rather pass the string representation of the path. This
is important because URI's that are not using the "file" scheme will cause the File(URI) constructor
to throw an exception.
