improve error reporting when a change script fails

[GoogleCodeExporter]

Currently, when applying db scripts directly to the database, the error 
reporting when a change script fails just includes the error message from the 
exception thrown by the database driver.

Many drivers have good error messages, many do not (including for example 
oracle).

The error message should include which script caused the error, which statement 
within the script, and ideally the sql text at fault.
