Title: Add a global module hook for raw client messages

This would be useful for my upcoming "smart" playback module that makes it possible for clients to avoid repeating the playback buffer on reconnect. It injects server-time message tag to all messages so that clients can keep track and request playback starting from the last received message before getting disconnected.
