updated bio for website

[Graham Percival]

Could somebody update my bio on web?  I can't find the web branch on my 
git, and as always I'd rather not fiddle with git if at all possible.

(I had a question from a translator, which made me realize that the bio 
was three years out of date.  For that matter, the other bios look 
pretty old too)

Cheers,
