presence and _availability_

Presence is the answer to a question: are you available?
This is contained in the "type" of presence: available/unavailable

Availability is an information how much available are you, and maybe
why. If you are at the console or away or busy, and maybe why are you
busy (working) or away (sleeping).

Avatar, the title of song you are listening and other crap is not part
of a presence, and a part of availability neither.

Sending those things in <presence/> stanzas just generate unnecessary
bandwidth usage, and generates presence-change events when presence or
availability is not changed at all.
