[Orgmode] Quote blocks face

[Julien Barnier]

Hi,

And first of all, thanks to everybody for this really great piece of
work that org-mode is. I think I discover a new feature almost every
day. :-)

I've got one little question : is there a simple way to customize the
face of some «environments» inside Emacs ? More precisely, I'd like to
make everything between #+BEGIN_QUOTE and #+END_QUOTE to be displayed
in italic...

Thanks a lot in advance,
