Deployment of principals.xml

[cybermaster]

Not a big deal, but I can't find a place from where principals.xml would be
deployed - I put it into applications/app, app/META-INF (where e.g.
application.xml resides, which *is* copied on deployment), app/app-web,
app/app-web/WEB-INF, but no go. Always need to replace the principals file
automatically created by Orions deployer in application-deployments/app

Maybe this is so on purpose - if not, I'd like to find out ...
