[TYPO3-core] RFC #15604: Install-Tool usability: db compare shows no errors when db-updates fail

[Xavier Perseguers]

Hi Ernesto,

> This is a SVN patch request.
>
> Type: Usability improvement
>
> BT reference: http://bugs.typo3.org/view.php?id=15604
>
> Branches: trunk
>
> Problem:
> If you compare your database with install tool and there are some issues
> found, you will not see if any errors occur. The only hint is a
> remaining update statement on the db-compare view.
>
> Pretty annoying if you are debugging why your extensions ext_tables.sql
> file doesn't work or if there is some DB error on the servers side.
>
>
> Solution:
> Display the error messages instead of ignoring the return values of the
> updater.

Beside a few minor CGL issues (e.g., space after comma - in existing but 
still patch modified code),

+1 by reading

Cannot test it at the moment but definitively a must have! Thanks
