Nui Arena Frames

[NynjaMonkii]

I was the one who mentioned the arena frames, and as I recently started using nUI again, I'm currently updating my set of arena frames to the new build of nUI. If Scott would allow me, I could post a patch of my changes, but I know distributing nUI+ myself is forbidden by the license terms (as would distributing my changes, which is why I need permission first).
