Follow a channel

[KyleMaas]

I noted Patchwork allows users to follow channels. I suppose we should probably support that, or at least support showing those follow messages. I just don't know what format the actual SSB messages are in.

Looks like they're messages like this:

content: {
  channel: "channel-name",
  subscribed: true,
  type: "channel"
}

Example: %PJsHSrHu/QrsjvJwg9AO5ppcDnE/XWKhd1yufoHaEEo=.sha256

This is actually pretty nice in that it pulls in content you might be interested in without following the people directly.

Content of that example message, for easier reference:

{
  "key": "%PJsHSrHu/QrsjvJwg9AO5ppcDnE/XWKhd1yufoHaEEo=.sha256",
  "value": {
    "previous": "%J2/T1Y8PBB5gUy+s46vA3Cal+8pAUTA2704AZxv1u+o=.sha256",
