SecureDrop Clients Can't Send/Receive messages to each other

[Harry-LeBlanc]

Currently, the only communication that exists is between the server instance of SecureDrop and the client. The SecureDrop clients need to be able to communicate with each other. I think a possible fix would be to have a function that sends the ports the server has seen all clients, and then they can use these ports with their handshake/send functions to build connections between them.
