User can create a public channel (a topic on our libp2p network)

[holmesworcester]

To create a channel, you:

• create a zcash address for the channel, with a viewing key.
• you create a Tor hidden service that will run until you leave the channel
• you run/join a libp2p/gossipsub network (on that hidden service only)
• you run an HTTP server (on that hidden service only)
• you are a member of the channel and have done everything necessary to join it.

The HTTP server will serve a git repo of known messages, and potentially a folder of files, but this is another issue.

Update: this is now just a network with a name.

User creates name. And user creates network.
