[XeTeX] Release 0.93 is available

[Jonathan Kew]

There's a new build of XeTeX available for you brave people...

* fixed potential crashing bug on trailing spaces in AAT text segments

* fixed bug causing T1Wrap tool (for .pfb font support) to fail on Far 
Eastern system

* fixed use of find in xdv2pdf so it shouldn't be confused by presence 
of Fink tools

* restored Mongolian OpenType shaping, which was missing from 0.9

* updated unicode-letters.tex to support Unicode 4.1 character 
repertoire

Enjoy!
