Persian fonts

[Kees van den Doel]

Hi all,

I updated the persian.ly init file with some more Persian "keys", instructions 
for setting up the fonts for the Mac (thank you Patrick) and some extended 
examples.

There are still plenty of problems, for example the Persian accidentals don't 
align well when you change the font size (apart from that they don't look that 
nice). Hopefully they will be integrated in 2.13 at some point.
