Directory Client Protocol

Core protocol is used as usual. Dirserv specific c2s/s2c protocol.

Continuum sends a sync request and SubSpace doesn't. The list request is sent as reliable. On the traditional directory servers (not catid's), traffic is always encrypted, even if you send a null encryption key.

Directory servers listen on port 4990 for client connections, and 4991 for updates to each zone's data using the Server to Directory Server Protocol as well as pings using the Ping Protocol.
