Add support for simple redirect

[kzxpr]

I'm not sure if this is covered by the proposal, but I would suggest that the URI scheme should also support some sort of simple redirect to an Actor's profile or an Activity Item on their native platform. Strictly speaking this is not an Activity Type.

I have use cases where I would like to be able to link deep into the user's familiar interface, e.g. when they press "ap+web:Actor:username@servername.tld" or "ap+web:Object:[some identifier]".

Also, this would make it possible to do a quick overall implementation - before supporting larger functionality, like a comment track.

You can create custom protocol schema for that. It'll look something like:

web+activitypub:nav%3AShow?
%40context%3Anav=https%3A%2F%2Fshow.schema%2Fv1&
object=acct%3Ausername%40servername.tld

Which decodes to this:

{
  "type": "nav:Show"
  "properties": {
    "@context:nav": "https://show.schema/v1",
    "object": "acct:username@servername.tld"
  }
}

Although I think it might be a good idea to not have any action at all to just call a view for some ap object.

web+activitypub:?object=acct%3Ausername%40servername.tld
