IMPORTANT CONSIDERATION

This file appears to be redundant and may be replaced by a dict handler that
would match task keyword to functions.

Or use it as a class Task

tasks_xmpp_chat =  {"check" : check_updates,
                    "status" : task_status_message,
                    "interval" : task_message}
tasks_xmpp_pubsub =  {"check" : check_updates,
                      "pubsub" : task_pubsub}

TODO

1) Deprecate "add" (see above) and make it interactive.
   Slixfeed: Do you still want to add this URL to subscription list?
   See: case _ if message_lowercase.startswith("add"):

3) Assure message delivery before calling a new task.
    See https://slixmpp.readthedocs.io/en/latest/event_index.html#term-marker_acknowledged

4) Do not send updates when busy or away.
    See https://slixmpp.readthedocs.io/en/latest/event_index.html#term-changed_status

5) Animate "You have X news items"
    📬️ when sent
    📫️ after sent

NOTE

1) Self presence
    Apparently, it is possible to view self presence.
    This means that there is no need to store presences in order to switch or restore presence.
