AllJoyn-2219: Flag security as off the org.freedesktop.DBus.Properties security is actually specified on the interface that defines the properties or the object itself not the properties interface. Also flag security as off for org.freedesktop.DBus.Peer because the "ping" method is always allowed.

Protect against attempt to dump and zeroed-out message, and a add timestamp to message debug info.
