Arabic-module -- update

[Karl Koehler <koehler or uni-bonn de>]

Hi !

I looked at the   nastalique urdu font  and added support for it, 
so now the speakers of persian among us might hopefully a little 
happier . Hopefully the mulefonts also work a little better,
peh, tcheh and gaf where fouled up and could not be rendered. 

You can download the improved arabic shaper from
	http://titan.informatik.uni-bonn.de/~koehlerk/u
Probably you will have to set up your .pangox-aliases to use the 
nastalique urdu font
( The same as for the langbox-font in a 'normal' configuration ).

best regards,
