Patch review: Pass args to block for render :layout

I'm looking for some feedback on this ticket. I know it will be useful
in my app, and I'm wondering if you will find it useful too.

It basically allows you to pass arguments to a block when using
"render :layout" in the view. See description on ticket for details.

Nice, very nice!
