new translator section in debian::weeklynews::footer

[Marek Łaska]

I was thinking about adding to d::w::footer another section, I mean 
translator(s). Very often DWN is translated by someone, who would like his 
name mentioned, especially if he doesn't translate ordinary Debian webpages 
but only DWN.
If no protests, I can do it, it would look much like editor(s) section.
