cgitb for the console.

[wqe]

I think cgitb is a great tool. Before things like boa came along, I used
it heavily for debugging. Anyway, I saw no reason that console error
mechanism should be worse than cgitb, so I cosmetically hacked through it
to stop outputting html.

Anyway, I think the python community process could help improve this code
so that it could eventually be part of the normal console error mechanism.
