[Development] Indicating Maintainers & Approvers on IRC

[marius.storm-olsen at nokia.com]

Hi,

Until now, voiced users on #qt-labs have indicated Nokia personnel, 
which was useful in the "old days" when only Nokians could merge patches 
into the codebase.

However, those days have passed, and I think it would be useful to 
re-purpose the op/voice to signify Maintainers, Approvers etc, to help 
contributors know who is what.

So, I propose that
     Chief Maintainer + Maintainers +
     Infra. tools Admins get Op status (@ prefix)
     Approvers get Voice status (+ prefix)

Or maybe there's other suggestions?
