New issue 1890 by [email protected]: Implement ErrorEvent interface for guest errors
http://code.google.com/p/google-caja/issues/detail?id=1890

There has been recent progress in changing the 'onerror' event handler to receive extra parameters describing the error.

The specification can be found: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#runtime-script-errors

And progress (for chromium) at https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/Li61lfcbWws

Although I haven't found any implementing browsers, I did notice that chrome as of version 34, sends 4 arguments to window.onerror (message, scriptUri, lineNo, colNo, errorObject).

I have included a patch that adds the colNo, and errorObject parameter to `onerror` calls.
