Thanks for your work on this feature!
Can you please point out what was backported from FLOW3 using the script?
I think it's fine if we have some deviations to FLOW3 here for
displaying errors using already existing methods and/or hooks.
Ingo, do you think that's possible?

@all others: Please test Ingo's patch. Don't concentrate on styling
issues or CGL issues. Send feedback whether the technical part serves
your demand for an error/exception handling in TYPO3 4.3.
Templating, styling (the most non-technical part) can be solved when
it's for sure that the feature does what it should do. Thanks!
