Need to pass in the render_frame, and have the ErrorHelper check if it's the
main frame, an pass that down to the ErrorHelperCode (A bit weird, but that's
needed for isolation of dependencies and error logic)

The NetErrorHelper already knows what RenderFrame it's observing though? Changed
the plumbing further inside NetErrorHelper, at any rate.

[mmenke, 2014/03/10 19:49:57]

Right...but this message may not be coming from the main render frame.

Done.
