[TYPO3-project-4-3] error reporting of ajax.php

[Martin Kutschker]

Hi!

I have two issues:

Any code that raises an error can only add an error message, but no
further structured detail. So I propose an alternative to <t3error>.

<t3fault>
  <code><code>
  <message>short message<message>
  <summary>longer message for the laymen<message>
  <details>technical deails for the expert (eg stack trace)<details>
</t3fault>

The other issue is that an error is sent with HTTP status 200 instead of
an error code like 500. ExtJS handlers who expect JSON will choke on the
XML data (and the format).

Comments?
