[XeTeX] XeSyriac: Syriac typesetting for XeLaTeX: alaph-test version

[Gareth Hughes]

The support for Aramaic numerals isn't really working yet, but has been
half written into xesyriac.sty. Thus, line 243 might cause problems, so
please comment it out if processing fails. It's probably easier to do
that for me to upload the font files for some code that doesn't work or
to cut the code out. I hope this is a temporary glitch, and I'll let the
list know when I've updated the code.
