New Art Lead, and announcing Release Manager

[Kaj Ailomaa]

We've recently added a new member to our team. So, let us all welcome Zak  
Frappan (madeinkobaia) as our new art team lead! For now, he's working on  
improving the artwork for our social sites.

Also, I would like to announce that smartboyhw is now our Release Manager.  
He'll be responsible for making sure our ISOs are complete, get tested and  
released. I'll also be adding him to our -dev team, giving him the  
possibility to fix bugs in our sources, if no one else is around, etc.

I've updated our Team Structure page  
https://wiki.ubuntu.com/UbuntuStudio/TeamStructure

Please note that the wiki is in progress on many areas. Many issues should  
be fixed within the next couple of days.
