 This hook gets called every time the client receives a message of type `name`. This can most notably be used with the new HTTP API call, "sendClientsMessage", which sends a custom message type to all clients connected to a pad. You can also use this to handle existing types.
 
 `collab_client.js` has a pretty extensive list of message types, if you want to take a look.
