[JDEV] Buddy Icon (Avatar) Proposal

[Julian Missig]

Ok, talked with temas and a few others.
I like 48x48, and temas said it wouldn't be a big deal if it were that way.

We're removing the type attribute, and the new list of supported formats is
gif|png|jpeg.

As for public XML storage, temas confirmed... there are still certain very
important servers which don't support public XML... these being the same
servers which don't support jabber:iq:browse. (Not that this annoys me or
anything ;) )
