updated the patch to the new specification. Changes: 

 - handler is called on every exceptional return, not just
TCL_ERROR (as it was before)
 - return code and result are appended as arguments to the
handler
 - registration command is now a subcommand of trace:

trace set exception ?-caught? ?-uncaught? ?command?
trace info exception
trace unset exception

The new patch is against CVS HEAD

added updating of error information before the custom
handler is run, so that the ::errorInfo variable contains it
when the handler is run.
