[XeTeX] bidi.sty for plain XeTeX

[heer]

 	Thanks to you all for the marvelous help you have given me on how 
to use bidi with plain xetex.  It's obvious to me now that I will have to 
upgrade my 2009 version of TeX Live.  I don't know why Ubuntu still makes 
available only this old version and not the latest version.  Fortunately 
John Was's suggestions have worked out very well with my old version of 
TeX Live and I can now make an Arabic file using xetex.
