[Webteam] Supporters page

[Andreas Raab]

Hi -

Here is the first version for the supporters page:

	http://www.squeak.org/Supporters

I'm not sure how people feel about linking the logos statically (in 
which case I'd need to know where to put them) or whether linking them 
from other places is fine.

If you think the page is reasonable (I think it is) we should add it to 
the main navigation menu so that it's accessible.

Cheers,
   - Andreas
