Adding glyphs to Arabic fonts

Hi Dave et al
I've added a page on the above as you suggested, and also included an (optional) appendix on installing FF on Ubuntu 14.04.  I also added a note to README to say you need ruby-dev installed before gem install jekyll will work.

OK, I've merged the appendix into the current Chapter 3.

Yes.  Jekyll will generate the page, but give a Not Found when you use the 
server to access it.  I converted in the penultimate commit so you can use 
that, but I've had to convert back again, because I need to see what I'm 
writing. :-)  That means any further commits will revert to --. :-(  Not sure 
how it's got onto the existing pages.

Done.
