[wildfly-dev] smaller footprints

Since the logging subsystem is in the core distro, I'm wondering if the
default DUP's to add logging dependencies and search for logging
configuration files in deployments should be disabled. There are
attributes to disable these now which are should remain enabled in
WildFly, but it seems the opposite might be preferable in a core-distro.
I've not really thought about how to do that or looked over Stuarts
branch with great detail, but just kind of throwing it out there to get
opinions on it.
