[jitsi-users] self-presence in contact list


having self-presence of other resources on the same XMPP account in the
contact list would be great.

Apart from talking to yourself, that would allow for the following

- Alice calls Bob via Jingle, on his desktop resource
- Alice and Bob tak for some time, then Bob has to catch the
   bus, but the two of them have not yet finished their talk
- Bob starts Jitsi on his Android device
- Bob triggers an unattended transfer to his self-presence on
   Android from his desktop
- After the transfer has finished, Bob shuts down his desktop
   system and continues his talk to Alice on his handset



<Natureshadow> Auf welchem Server liegt das denn jetzt…?
<mirabilos> Wenn es nicht übers Netz kommt bei Hetzner, wenn es nicht
            gelesen wird bei STRATO, wenn es klappt bei manitu.
