Arabic localizations.  Did this one without adult supervision and got lost along the way, eventually manually naming the ar.lproj folder before scratching everything and starting over... there was also a problem with the language "Arabic (world)" not working, so I had to do it all again (again), which I think is why there are like twice as many new files in this commit than are necessary.  Pretty sure I did it right this time, but... just be really careful in accepting this.

Jesus, I feel like my mom.  How do I google an email with Yahoo?
