Have editable feed names

[sknebel]

When individual feeds become more visible (by being shown as a source (#13) and by being individually fetchable (#21)), they should have a name property, and the user should be able to set it manually.

Some related discussion from #indieweb-dev IRC today: https://chat.indieweb.org/dev/2019-04-18#t1555616799486800

Briefly, @cleverdevil suggested adding metadata including icons, name/title, description, etc.

Critically, I’d say that the population of the metadata could be automated on the server, optionally, but just having it available in the API for clients would be a great start.

Aperture now supports editable feed names via its UI. The feed names are returned in the Microsub response:

?action=follow&channel=XXX

{
  "items": [
    {
      "type": "feed",
      "url": "http://tantek.com/",
      "name": "Tantek Çelik"
    },
    {
      "type": "feed",
      "url": "https://adactio.com/",
      "name": "Jeremy Keith"
    }
  ]
}

If there is no name set for the channel, it won't include the property. I didn't add a Microsub action to set the feed name yet.
