stderr/stdout handling on Windows
- An application needs to be built with 'console' for stderr/stdout to appear (use Creator's "Run in terminal" setting)
- Creator itself is built with 'console' in debug mode only.
- qDebug() prints to stderr for ‘console’ apps, else to the Windows debugger log, which can be shown with the DbgView utility
