Avatar: provide common logic for uploading; don't store Connection

Although the setting part of the work is class(User or Room)-specific, the uploading part is common, so Avatar provides it now.
Also: there's no need to store Connection, as it's only used in get() and upload() - just pass it as the parameter to the methods.
