If a user has a current avatar, and sso_overrides_avatar is true, but no avatar_url is
passed in the sso attributes, the current code errors, as it tries to parse a nil
as a URL. It seems to me valid that a third party system may not pass an avatar_url in
some cases (e.g. avatars may not be mandatory, so not all users may have them)
This might warrant a discussion about what should happen in this case; maybe the current
avatar in discourse should be removed? This branch merely stops the login process erroring.
Implemented by having Discourse download the image from the provided URL
and treating it as a custom upload.
Adds two more parameters to the SSO site’s response:
* `avatar_url` specifies the URL of the overriding avatar.
* `avatar_force_update` Discourse does not re-download avatars that
has already been download from the same URL. Setting this to true forces
Discourse to re-download the avatar in `avatar_url`
Note that both parameters are ignored if `sso_overrides_avatar` is set
to false.
