unhandled xforms exceptions should get dumped to the JS console

i'm not quite sure how we would implement this, but it seems like it might be a
good idea.

I discussed this with smaug recently, and also think we should have a default
handler of sorts, and the JS Console could be a good target. No design
propoposal from me either :)

This adds a way to dump the name of the unhandled exception, but
something more is needed. Document URL and maybe event target?
And of course, how do we decide when an event is actually unhandled?

The main question here is, how we should report the errors.

If the form is invalid, we don't want to present the end user with a broken,
non-functional form.  Perhaps replace the page with a error page?  Or an alert?

We might want to send a more detailed error to the js console.  Question is, can
we figure out what line the error is on?

This bug seems to have two real issues:
1. add error output to js console, which is bug 287714
2. better inform user of fatal errors, which is bug 290465

So I'm duping to bug 290465.
