Room discovery

[nesium]

I believe that a MUC service only ever returns public rooms: https://xmpp.org/extensions/xep-0045.html#disco-rooms

From a user perspective however when browsing channels I would expect to see private channels, that I've been invited to, as well.

We could of course list all public channels as well as private channels from the user's bookmarks. That begs the question if the server should automatically create a bookmark for a user when that user is invited to a channel.

Here's what HipChat did in the past…

<!-- Client -->
<iq type="get" to="conf.hipchat.com">

<!-- Server -->
<iq from='conf.hipchat.com' type='result' to='1_1@chat.hipchat.com/mac'>
  <query xmlns='http://jabber.org/protocol/disco#items'>
