AutoTest: Provide way to access the original test output

When running tests the original output is processed and not presented
to the user at all. For crashing tests this could mean that output
was not able to get processed completely (e.g. when having XML as
output and relying on well-formed code)
Unhandled output could also lead to incorrect results.
This patch adds another view to the results pane which contains
the complete output of the last test run.
