mod_vcard_muc: Add an alternative method of signaling avatar change
When the avatar has been changed, a signal is sent that the room
configuration has changed. Clients then do a disco#info query to find
the SHA-1 of the new avatar. They can then fetch it as before, or not if
they have it cached already.
This is meant to be less disruptive than signaling via presence, which
caused problems for some clients.
If clients transition to the new method, the old one can eventually be removed.
The namespace is made up while waiting for standardization.
Otherwise it is very close to what's described in
