Add protocol extension with UUIDs This system can easily be extended by independent authors without collisions, something the old system with plain increasing integers did not allow. Do this by utilizing the previously unused message code `NETMSG_NULL` which has a value of 0. This works for engine and game messages, snapshot items and events.

Properly initialize all `CClient` member variables Additionally, ensure snapshots are cleared and dummy is disconnected when disconnecting programatically with `DisconnectWithReason`. Add `NETADDR_ZEROED` and `UUID_ZEROED` for more convenient initialization without using `mem_zero`.
