mod_pubsub_post: Restructure authentication and authorization (BC) This deprecates the default "superuser" actor model and makes the default equivalent to the previous "request.id". A single actor and secret per node is supported because HTTP and WebHooks don't normally include any authorization identity. Allowing authentication bypass when no secret is given should be relatively safe when the actor is unprivileged, as will be unless explicitly configured otherwise.

# Introduction

This module exposes users [microblogging][xep277] on Prosodys built-in HTTP server.

# Configuration

The module itself has no options. However it uses the access control
mechanisms in PubSub, so users must reconfigure their microblogging node
to allow access, by setting `access_model` to `open`.
E.g. Gajim has UI for this, look for "Personal Events" → "Configure
services".
