POV-ray section: erratum

[olivier at linuxgraphic.org]

how confusing: there's a subject I forgot to mention: the full credits for the 
website design and all the presentations/topics/subjects should go to Olivier 
Boyaval, from the same team than me, an early POV enthusiast. I wrote only the 
tutorials and made a few corrections/additions, along with all the english 
transtlations, but most of the credits should go to him, particularly about the 
*great* layout of the section...
In case you'd want to send some congratulations: olivierb at linuxgraphic.org ;o)
beware the e-mail is almost the same than mine! :oD

Cheers,
OlivS
