Zack Rusin is a WebKit Reviewer for the Qt Port

Zack Rusin is now a qualified reviewer for Qt platform code in WebKit. Although he has not yet submitted many patches to WebKit as such, he has a long history working with KHTML and did much of the Unity porting work originally. As such, he is likely one of the best reviewers for Qt platform code. Congrats, Zack, and thank you.
