Allow multiple copies of things on different namespaces

[awrichar]

Everything that can be sent (messages, data, all definition types) needs to only be unique within a namespace. The IDs can no longer be considered globally unique, and the database needs to reflect that.

Move "node" configuration to the "multiparty" section (next to "org"), as different namespaces may want to advertise different names for their local node.

Clean up operation handling in DX to make it consistent with other plugins.
