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"):

2) If subscription is inadequate (see XmppPresence.request), send a message that says so.

3) Set timeout for moderator interaction.
   If moderator interaction has been made, and moderator approves the bot, then
   the bot will add the given groupchat to bookmarks; otherwise, the bot will
   send a message that it was not approved and therefore leaves the groupchat.
