Avatar of remote user is not loaded
When a remote user is created, an avatar image should be loaded (and cached perhaps, but at least its URL should be saved for display!). Currently, even when the remote user's Atom feed contains a <logo>, and multiple <link rel="avatar" type="image/png" href="..." /> fields with correct, working image URLs, a default "no avatar" image is displayed on GNU Social.
This doesn't appear to be a problem when the remote user is from another GNU Social instance. This makes me suspect that the code that loads this data correctly is using the users/show.json URL, which is not part of any standard, and that the code that should load this from the Atom feed is broken.
