test failures were caught in a try-catch-finally construct,
letting the build succeed even when unit tests failed.

I also corrected the behavior of escaping in the command
lines for external processes (use \), and I've defensively
modified the code in ExecuteExternalDialog to not call
DirectoryChooser.setSelectedFile so early, even though
that appears to be a Swing bug to me.
