patch docs for 0.5.x tutorial based on #740

I hit these issues while looking at the docs in s3, so thought I'd change them around a bit.  Not sure if you want to go with berkeleydb-es as the most basic conf file for the intro tutorial, but I'm not sure if local storage still exists.  Also, I don't know if ../db has to exist before running this, as I had already modified the .properties file to other paths.
