[patch] Reversing numbers in arabic_arabi

[Dov Feldstern]

Hi!

Attached find a patch which I believe is necessary for correctly 
displaying numbers in the output of arabic documents using Arabi 
(ArabTeX takes care of this internally).

Uwe, Mostafa --- could you please test this? (I'm still having trouble 
with setting up Arabi correctly --- though what I am able to see 
convinces me that this patch is needed).

This is technically a format change, though I would again argue that we 
should *not* create a lyx2lyx for it. However, if this is not 
acceptable, a lyx2lyx patch should be relatively simple; and that only 
underlines the need for applying this before 1.5.0.
